An approach to robot welding path autonomous planning of the intersection weldment based on 3D visual perception

To improve the accuracy, an approach to robot welding path planning of the intersection weldment based on 3D visual perception is proposed. It adopts the two-stage location scheme of “global 3D reconstruction + local scanning correction”. First, this paper proposes an improved K-means clustering method based on the geometric features of workpiece point-cloud, to achieve accurate and fast point-cloud segmentation. Second, the intersection parameters of workpiece can be quickly calculated by the proposed parameter identification method. Third, this paper plans the scanning path of laser scanner according to the identified parameters, and puts forward an algorithm of weld path points recognition combined with the actual weldments state. Then, the pose of robot welding torch is obtained by using spline fitting algorithm and welding torch attitude estimation algorithm. Finally, the experiments show the path planning error is about 0.3 mm, which has increased a lot than the published methods.

Multi-vessel Target Tracking with Camera Fusion for Unmanned Surface Vehicles

With the decreasing availability of sailors, there has been an increasing focus on the development of autonomous ships. Among the various components of autonomous ships, automatic recognition systems that can replace human vision are a crucial area of research. While ongoing studies utilize traditional perception sensors such as RADAR (RAdio Detection And Ranging) and AIS (Automatic Identification System), they have limitations such as blind spots and a restricted detection range. To address these limitations, this paper proposes a new recognition method that utilizes multiple cameras, including Electro-Optical and Infrared cameras, to supplement traditional perception sensors. This method aims to detect maritime obstacles accurately and estimate their dynamic motion using a tracking process. Initially, real-sea images were collected for maritime obstacle detection, and a deep-learning-based detection model was trained on them. The detection results were then employed in an adaptive tracking filter, which allowed the precise motion estimation of the obstacles. Furthermore, to compensate for the limitations of using individual cameras as sensors, this study introduces the simultaneous fusion of tracked data from multiple cameras. This fusion process enhances tracking results in various ways. In field tests using multiple Unmanned Surface Vehicles (USVs), the proposed method successfully converged tracking results within the range of GPS errors. In addition, the fusion of tracked data from multiple cameras significantly improved the tracking results obtained from a single camera.

Efficient analysis of deep neural networks for vision via biologically-inspired receptive field angles: An in-depth survey

Efficient feature extraction is a pivotal requirement for Deep Neural Network (DNN) models, particularly in the realm of visual tasks where effective feature extraction relies on well-designed receptive fields. Nevertheless, the evaluation and fulfillment of the criteria for “effective receptive fields”, along with their essential conditions, continue to pose numerous unresolved mysteries. In this Analysis we amalgamated principles from the field of biologically inspired vision to reevaluate the role of receptive fields within neural networks, and have proposed a comprehensive design theory aimed at characterizing and guiding the research of efficient DNNs. Our design theory draws from both the principles of biological vision and the latest advances in DNN design theory. It encompasses five fundamental axes of receptive field design research: the Global Artificial Neuron Workspace (GANW), Layered Processing Theory (LPT), Multi-Receptive Field Integration Design (M-RFID), Heterogeneous Receptive Field (HRF), and Receptive Field Plasticity Theory (RFPT). We have applied these design theories to validate traditional and cutting-edge neural networks, conducting in-depth analyses of the outcomes to provide a summary of the current landscape of research on visual receptive fields. Furthermore, we have classified current visual receptive fields into three categories: sample-specific local receptive fields, global spatial receptive fields, and adaptive dynamic receptive fields. From the perspective of perceptual fields and network lightweight design, we have introduced some classic and state-of-the-art DNN models, with a particular emphasis on those employing innovative algorithms that have yielded the most recent achievements. We have concluded by highlighting the key areas of interest in the field of visual receptive fields for future research endeavors.

Effects of repetitive transcranial magnetic stimulation of the right inferior parietal lobe on the body image perception in anorexia nervosa: A pilot randomized controlled study.

Restrictive anorexia nervosa (AN) is associated with distorted perception of body shape, previously linked to hypoactivity and reduced excitability of the right inferior parietal lobe (rIPL). Here, we investigated the impact of high-frequency repetitive transcranial magnetic stimulation (HF rTMS) of the rIPL on body shape perception in patients with AN. Seventeen patients with AN (median [Q1_Q3] age, 35 [27_39] years; disease duration, 12 [6_18] years) were randomly assigned to receive real or sham HF (10Hz) rTMS of the rIPL over a period of 2weeks, comprising 10 sessions. The primary outcome measure was the Body Shape Questionnaire (BSQ). Secondary outcomes included eating disorder symptoms, body mass index, mood, anxiety, and safety. Data collection were done at baseline, post-rTMS, and at 2weeks and 3 months post-rTMS. Following both real and sham rTMS of the rIPL, no significant differences were observed in body shape perception or other parameters. Both real and sham rTMS interventions were deemed safe and well tolerated. Notably, serious adverse events were associated with the underlying eating and mood disorders, resulting in hospitalization for undernutrition (five patients) or suicidal attempts (two patients). This pilot study does not support the use of rTMS of the rIPL as an effective method for improving body shape perception in individuals with the restrictive form of AN. Further research is warranted to comprehensively explore both the clinical and neurophysiological effects of HF rTMS in this population.

A Novel Electrical Equipment Status Diagnosis Method Based on Super-Resolution Reconstruction and Logical Reasoning.

The accurate detection of electrical equipment states and faults is crucial for the reliable operation of such equipment and for maintaining the health of the overall power system. The state of power equipment can be effectively monitored through deep learning-based visual inspection methods, which provide essential information for diagnosing and predicting equipment failures. However, there are significant challenges: on the one hand, electrical equipment typically operates in complex environments, thus resulting in captured images that contain environmental noise, which significantly reduces the accuracy of state recognition based on visual perception. This, in turn, affects the comprehensiveness of the power system's situational awareness. On the other hand, visual perception is limited to obtaining the appearance characteristics of the equipment. The lack of logical reasoning makes it difficult for purely visual analysis to conduct a deeper analysis and diagnosis of the complex equipment state. Therefore, to address these two issues, we first designed an image super-resolution reconstruction method based on the Generative Adversarial Network (GAN) to filter environmental noise. Then, the pixel information is analyzed using a deep learning-based method to obtain the spatial feature of the equipment. Finally, by constructing the logic diagram for electrical equipment clusters, we propose an interpretable fault diagnosis method that integrates the spatial features and temporal states of the electrical equipment. To verify the effectiveness of the proposed algorithm, extensive experiments are conducted on six datasets. The results demonstrate that the proposed method can achieve high accuracy in diagnosing electrical equipment faults.

AESTHETIC ASPECTS OF IDEAL IMAGE IN THE PHILOSOPHICAL CONCEPTS OF RENAISSANCE

The article analyzes the aesthetic aspects of the ideal as a reflection of the subjective concept within the philosophical concepts of Renaissance thinkers N. Kuzansky, M. Ficino, L. Alberti, L. da Vinci. The author considered certain aesthetic aspects in the context of the categorical trinity "ideal-beautiful-beautiful". This study can become the basis for the study of the Renaissance individual in terms of his active worldview of the essential and pragmatic basis of existence, having absolute vision, capable of creating ideal images. The relevance of the work is due to the interest in the study of this aspect of applied aesthetics both in our country and abroad in connection with the scientific development of the study of human capabilities. The purpose is to analyze and study the concepts of Renaissance philosophers to reveal the meaning of the trinity "ideal-beautiful-beautiful" in the context of actualization of the study of the ideal image at subjective-individual visual perception. Materials and methods. The method of research is comparative analysis; method of interpretation of scientific philosophical works; method of synthesis and analogy. Results. The works of Renaissance thinkers were studied in order to clarify the concept of ideal image. It is shown that ideal images materialize in the subjective space of an individual in objects, as their pragmatic value-oriented component is highlighted in a number of objects similar to it. The signs of the ideal or absolute in the object, which became part of the essential basis of objective reality in the Renaissance, are analyzed, the qualities of the person of this era are highlighted, and his ideality in the subjective space is defined.

The Impact of Temporal Light Modulation on Psychological Responses Assessed by the Stroboscopic Visibility Measure

ABSTRACT With the advent of LED lighting systems, short-term psychological responses to temporal light modulation (TLM) in offices have attracted considerable research attention in recent years. The stroboscopic visibility measure (SVM) is a leading metric for predicting the visibility of stroboscopic effects, one of visual perception effects of TLM. However, research is lacking to link TLM with potential psychological responses using the SVM metric. In this study, 10 participants joined in the experiments under 6 SVM levels (SVM: ~0.060; ~0.500; ~1.000; ~1.500; ~2.500; ~3.868) finishing tasks of subjective general rating, moving objects observation, sustained attention visual task, visual fatigue scale and PANAS (Positive and Negative Affect Scales). This study found that the SVM metric significantly evaluated the impact of TLM on psychological responses related to lighting ambiance and the moving objects observation. As expected, the stroboscopic visibility and motion dispersion scores increased with increasing SVM levels in the observation of rotating disc, and detectable stroboscopic effects were found to have negative effects on visual and work performances. However, the results of sustained attention visual task indicated that the SVM metric performed poorly in predicting the effects of TLM related to the eye saccades. High SVM levels were associated with negative experiences of lighting coziness, cognition performance and stroboscopic perception during moving objects observation. The scores were close to the expected at ~ 1.000 but exhibited a non-linearly increase with higher SVM levels. This study contributes valuable data to the ongoing discussions on setting limits for allowable modulation in practical lighting applications.

RICE: A Dataset and Baseline for Cloud Removal in Remote Sensing Images

Removing clouds is an essential preprocessing step in analyzing remote sensing images, as cloud-based overlays commonly occur in optical remote sensing images and can significantly limit the usability of the acquired data. Deep learning has exhibited remarkable progress in remote sensing, encompassing scene classification and change detection tasks. Nevertheless, the appli-cation of deep learning techniques to cloud removal in remote sensing images is currently con-strained by the limited availability of training datasets explicitly tailored for neural networks. This paper presents the Remote sensing Image Cloud rEmoving dataset (RICE) to address this challenge and proposes baseline models incorporating a convolutional attention mechanism, which has demonstrated superior performance in identifying and restoring cloud-affected regions, with quantitative results indicating a 3.08% improvement in accuracy over traditional methods. This mechanism empowers the network to comprehend better the spatial structure, local details, and inter-channel correlations within remote sensing images, thus effectively addressing the diverse distributions of clouds. Moreover, by integrating this attention mechanism, our models achieve a crucial comparison advantage, outperforming existing state-of-the-art techniques in terms of both visual quality and quantitative metrics. We propose adopting the Learned Per-ceptual Image Patch Similarity metric, which emphasizes perceptual similarity, to evaluate the quality of cloud-free images generated by the models. Our work not only contributes to advancing cloud removal techniques in remote sensing but also provides a comprehensive evaluation framework for assessing the fidelity of the generated images.

Self-Perception Profile, Body Image Perception and Satisfaction in Relation to Body Mass Index: An Investigation in a Sample of Adolescents from the Campania Region, Italy

(1) Background: Body image dissatisfaction has been commonly reported in adolescents with overweight/obesity and has been related to a lack of motivation to change lifestyle behaviors. Plus, a better perception of physical fitness has been related to a higher self-perception in physical aspect and social items in youths. (2) Methods: A total of 120 (59.2% males, mean age of 12.3 ± 0.9 years) middle-school adolescents participated in the present study. Anthropometric measurements were assessed following the standard procedures. Body weight perception and body image satisfaction were assessed using the Silhouette Figure Body Images Test. Self-perception profile, perceived physical fitness, and perceived difficulties in conducting physical tasks were assessed by using structured questionnaires. (3) Results: Overweight was present in 27.5% adolescents and obesity in 32.5%. A total of 89.7% of adolescents with obesity did not have a real perception of his/her weight status and 84.6% of adolescents with obesity were not satisfied with his/her body image. The self-perception of physical appearance, perceived difficulties in running, perceived overall fitness, and perceived speed/agility were lower in adolescents who were unsatisfied with their body image. Body image satisfaction was positively associated with the self-perception of physical appearance and overall fitness and negatively associated with perceived difficulties in running, independently of sex, age, and BMI. (4) Conclusions: Adolescents with obesity did not have a real perception of their weight status and were unsatisfied with their body image. The positive association between body satisfaction, a better perception of overall fitness, and less difficulties in conducting physical tasks suggests the protective role of the components of physical activity and health-related fitness on body acceptance in a critical period of life.

The Glance: Kinaesthetics, Emergence and Power

Why differentiate “glancing” from “gazing”? This translation and rendition of a text that has appeared only in Portuguese considers the distinctiveness of the glance in the Western tradition of visualicity, power, knowledge and gender. While the glance has been acknowledged in visual studies and phenomenology, twenty years on from the original publication there are few sustained attempts to consider its role in the repertoire of visualicity or the ways that the glance is an example of aesthesis: it connects kinaesthetic experience to knowing and to sociality or relationality. Foucault, Hegel, Nietzsche and Kierkegaard cite the glance as a flash (de Koonig) of power-knowledge and its exercise, generally as an attribute of masculinity (Hegel) or authority (Foucault). The glance is liminal foresight into the coming moment as a scan of the visual present as well as an anticipatory search. It expresses desire and is attracted by visual stimulii, knotting affect to visual physiology. The glance is additionally tactical, anxious and furtive, an exercise in counterpower that seeks to “rotate the world on its axis” (Buber) in a way that repositions subjects and objects of the glance in a relation.

Translating Difference: Reflections on the Interface between Novelistic Discourse and World Literature

The present essay examines two moments from the evolution of the modern Malayalam novel, in relation to the reception of two classics in world literature, namely Victor Hugo’s Les Misérables translated into Malayalam between 1925 and 1927 and García Márquez’s One Hundred Years of Solitude translated in 1984. The translation of Hugo’s novel energized the scene of Malayalam fiction by infusing new modes of representation and widening the intellectual horizons of writers in general, and novelists in particular. The echoes of Les Misérables could be heard in Malayalam fiction well into the 1950s. The struggles against colonial and feudal authorities in Kerala, provided a fertile context for the imaginative interpretation of Hugo’s humanist vision. The paper illustrates this point through close readings of critical essays, autobiographical narratives and debates on the nature of translation. The fascination of Malayali readers with García Márquez has resulted in the translation of his entire corpus into Malayalam. Magic realism as pioneered by García Márquez liberated the Malayalam novelistic narrative from social realist and modernist dogmas. The colonial disruption of oral narratives, the consequent cultural amnesia and the struggle to reclaim one’s forgotten past are themes that struck a chord in Malayalam writers of fiction. Through a detailed discussion of the novel, Moustache by S. Hareesh, the interface between novelistic discourse and world literature is mapped in the latter part of the essay.

Visual Cortical Thickness Increases with Prolonged Artificial Vision Restoration.

The Argus II retinal prosthesis restores visual perception to late blind patients. It has been shown that structural changes occur in the brain due to late-onset blindness, including cortical thinning in visual regions of the brain. Following vision restoration, it is not yet known whether these visual regions are reinvigorated and regain a normal cortical thickness or retain the diminished thickness from blindness. We evaluated the cortical thicknesses of ten Argus II Retinal Prostheses patients, ten blind patients, and thirteen sighted participants. The Argus II patients on average had a thicker left Cuneus Cortex and Lateral Occipital Cortex relative to the blind patients. The duration of the Argus II use (time since implant in active users) significantly partially correlated with thicker visual cortical regions in the left hemisphere. Furthermore, in the two case studies (scanned before and after implantation), the patient with longer device use (44.5 months) had an increase in the cortical thickness of visual regions, whereas the shorter-using patient did not (6.5 months). Finally, a third case, scanned at three time points post-implantation, showed an increase in cortical thickness in the Lateral Occipital Cortex between 43.5 and 57 months, which was maintained even after 3 years of disuse (106 months). Overall, the Argus II patients' cortical thickness was on average significantly rejuvenated in two higher visual regions and, patients using the implant for a longer duration had thicker visual regions. This research raises the possibility of structural plasticity reversing visual cortical atrophy in late-blind patients with prolonged vision restoration.

Alterations in neural activation in the ventral frontoparietal network during complex magnocellular stimuli in developmental dyslexia associated with READ1 deletion

BackgroundAn intronic deletion within intron 2 of the DCDC2 gene encompassing the entire READ1 (hereafter, READ1d) has been associated in both children with developmental dyslexia (DD) and typical readers (TRs), with interindividual variation in reading performance and motion perception as well as with structural and functional brain alterations. Visual motion perception -- specifically processed by the magnocellular (M) stream -- has been reported to be a solid and reliable endophenotype of DD. Hence, we predicted that READ1d should affect neural activations in brain regions sensitive to M stream demands as reading proficiency changes.MethodsWe investigated neural activations during two M-eliciting fMRI visual tasks (full-field sinusoidal gratings controlled for spatial and temporal frequencies and luminance contrast, and sensitivity to motion coherence at 6%, 15% and 40% dot coherence levels) in four subject groups: children with DD with/without READ1d, and TRs with/without READ1d.ResultsAt the Bonferroni-corrected level of significance, reading skills showed a significant effect in the right polar frontal cortex during the full-field sinusoidal gratings-M task. Regardless of the presence/absence of the READ1d, subjects with poor reading proficiency showed hyperactivation in this region of interest (ROI) compared to subjects with better reading scores. Moreover, a significant interaction was found between READ1d and reading performance in the left frontal opercular area 4 during the 15% coherent motion sensitivity task. Among subjects with poor reading performance, neural activation in this ROI during this specific task was higher for subjects without READ1d than for READ1d carriers. The difference vanished as reading skills increased.ConclusionsOur findings showed a READ1d-moderated genetic vulnerability to alterations in neural activation in the ventral attentive and salient networks during the processing of relevant stimuli in subjects with poor reading proficiency.

Detection of Mild Cognitive Impairment Through Hand Motor Function Under Digital Cognitive Test: Mixed Methods Study.

Early detection of cognitive impairment or dementia is essential to reduce the incidence of severe neurodegenerative diseases. However, currently available diagnostic tools for detecting mild cognitive impairment (MCI) or dementia are time-consuming, expensive, or not widely accessible. Hence, exploring more effective methods to assist clinicians in detecting MCI is necessary. In this study, we aimed to explore the feasibility and efficiency of assessing MCI through movement kinetics under tablet-based "drawing and dragging" tasks. We iteratively designed "drawing and dragging" tasks by conducting symposiums, programming, and interviews with stakeholders (neurologists, nurses, engineers, patients with MCI, healthy older adults, and caregivers). Subsequently, stroke patterns and movement kinetics were evaluated in healthy control and MCI groups by comparing 5 categories of features related to hand motor function (ie, time, stroke, frequency, score, and sequence). Finally, user experience with the overall cognitive screening system was investigated using structured questionnaires and unstructured interviews, and their suggestions were recorded. The "drawing and dragging" tasks can detect MCI effectively, with an average accuracy of 85% (SD 2%). Using statistical comparison of movement kinetics, we discovered that the time- and score-based features are the most effective among all the features. Specifically, compared with the healthy control group, the MCI group showed a significant increase in the time they took for the hand to switch from one stroke to the next, with longer drawing times, slow dragging, and lower scores. In addition, patients with MCI had poorer decision-making strategies and visual perception of drawing sequence features, as evidenced by adding auxiliary information and losing more local details in the drawing. Feedback from user experience indicates that our system is user-friendly and facilitates screening for deficits in self-perception. The tablet-based MCI detection system quantitatively assesses hand motor function in older adults and further elucidates the cognitive and behavioral decline phenomenon in patients with MCI. This innovative approach serves to identify and measure digital biomarkers associated with MCI or Alzheimer dementia, enabling the monitoring of changes in patients' executive function and visual perceptual abilities as the disease advances.

Age-related changes in the susceptibility to visual illusions of size.

As the global population ages, understanding of the effect of aging on visual perception is of growing importance. This study investigates age-related changes in adulthood along size perception through the lens of three visual illusions: the Ponzo, Ebbinghaus, and Height-width illusions. Utilizing the Bayesian conceptualization of the aging brain, which posits increased reliance on prior knowledge with age, we explored potential differences in the susceptibility to visual illusions across different age groups in adults (ages 20-85 years). To this end, we used the BTPI (Ben-Gurion University Test for Perceptual Illusions), an online validated battery of visual illusions developed in our lab. The findings revealed distinct patterns of age-related changes for each of the illusions, challenging the idea of a generalized increase in reliance on prior knowledge with age. Specifically, we observed a systematic reduction in susceptibility to the Ebbinghaus illusion with age, while susceptibility to the Height-width illusion increased with age. As for the Ponzo illusion, there were no significant changes with age. These results underscore the complexity of age-related changes in visual perception and converge with previous findings to support the idea that different visual illusions of size are mediated by distinct perceptual mechanisms.

The collective-man of res publica. Norwid and the civic society

The intellectually and politically tempestuous crystallization of the civic ideal in the nineteenth and twentieth century manifested not only in Europe (especially Western), but also in North and Middle America, and in time – all over the globe. An intense search for the “civic ideal” is clearly discernible in societies comprising the former Polish Republic, whose demise towards the end of the eighteenth century and the subsequent phases of its increasingdecompositionnot only failed to annihilate the republican tradition but in fact intensified authentic debate on possible roads toward modern society in the future independent state. A key role in this important dialogue was played by representatives of the landed gentry and the intelligentsia, the latter emerging in the nineteenth century as a new social formation that basically had no exact counterpart in other countries. In time, a few representatives of other classes also joined this dialogue on the shape of the future Polish state. What is the meaning of the phrase “civic society”? Today, it is used almost naturallyby columnists and politicians representing various positions, but it was virtually non-existent during Norwid’s lifetime, although the very ideaof organizing collective life on the basis of “civic” virtues has an almost immemorial provenance. This article attempts to describe Norwid’s civic thought, mainly by analysing his discursive statements, chiefly in journalism. Norwid was decidedly opposed to any doctrinaire elevation of “humanity” (which he called a “holy abstraction”) over “nation” and “Church,” through which individuals can actually partake in “the work of ages.” Another area in which Norwid struggled to develop clear civic categories comprises visions of humanity’s universal happiness and/or its apocalyptic fall, many of which were promulgated at the time. In his polemics with utopias of “fulfilled history” it is possible to discern clear echoes of ideological debates held at the time, especially ones between mystical and political visions used by various “prophets” to describe the ultimate perspectives for the development of current events whose subject is “humanity” – a category replacing “nations,” which would be thus seen as ending their historical “mission.”From this angle, Norwidwould criticise Skład zasad[A collection of principles] by Adam Mickiewicz– a manifesto of revolutionary transformations of civic rights, which are part of the legacy of the French Declaration of the Rights of Man and of the Citizen.In a letter to Józef Bohdan Zaleski, dated 24 April 1848, Norwid expressed his outrage at most theses contained in Skład, which he saw as undermining traditional values such as “homeland,” “property,” “lineage,” “nation,” etc.

Algorithmic Implementation of Visually Guided Interceptive Actions: Harmonic Ratios and Stimulation Invariants

This research presents a novel algorithmic implementation to improve the analysis of visually controlled interception and accompanying motor action through the computational application of harmonic ratios and stimulation invariants. Unlike traditional models that focus mainly on psychological aspects, our approach integrates the relevant constructs into a practical mathematical framework. This allows for dynamic prediction of interception points with improved accuracy and real-time perception–action capabilities, essential for applications in neurorehabilitation and virtual reality. Our methodology uses stimulation invariants as key parameters within a mathematical model to quantitatively predict and improve interception outcomes. The results demonstrate the superior performance of our algorithms over conventional methods, confirming their potential for advancing robotic vision systems and adaptive virtual environments. By translating complex theories of visual perception into algorithmic solutions, this study provides innovative ways to improve motion perception and interactive systems. This study aims to articulate the complex interplay of geometry, perception, and technology in understanding and utilizing cross ratios at infinity, emphasizing their practical applications in virtual and augmented reality settings.
