Concept Of Image Research Articles

바타유의 비정형 개념과 탈재현적 신체 이미지와의 상관성 연구

This paper aims to examine the correlation between the nonrepresentational body image in modern art and Georges Bataille’s concept of ‘the formless’. Therefore, Chapter 2 defines the concept of the nonrepresentational body image and examines cases in art history. In addition, by discussing the correlation between post structuralism and the nonrepresentational body image, the basis for the involvement of the body’s nonrepresentation in modern art is laid out. Chapter 3 discusses the analytical basis of the nonrepresentational body image by examining Georges Bataille’s concept of ‘the formless’ and its practical strategy, which provides a key element in the analysis of works. Chapter 4 analyzes the nonrepresentation of the body image in modern art based on Georges Bataille’s theory, as discussed above. Through this, the researcher presents the appearance of modern people whose nonrepresentational body image in the works of sample artists cross the boundary between the subject and the other as a sensory trace of the formless body, and it was found that behind it was the ‘Concept of Transgression’, which presupposes Georges Bataille’s negativity.

Tärähdyttävät sankarit New Yorkin maailmannäyttelyssä 1939 – Mieskuoro Finlandia Suomen maakuvan viestijänä

At the opening of the Finnish section of the New York World’s Fair on May 4, 1939, the Finlandia Male Chorus performed; the choir had been founded especially for the trip to North America, and in particular for performing at the New York World’s Fair. In addition to general coverage in the press, the choir’s travel plans, its preparations, and the trip itself were followed on many different radio broadcasts. What did Mieskuoro Finlandia want to tell about Finland at the New York World’s Fair in the spring of 1939? How was the choir founded, how did it work towards the goal of its journey, and what did it do afterwards? Answers to these questions are sought here especially through the concepts of cultural diplomacy and country image. According to the article, the Finlandia Male Chorus’ activities serve as a good example of the creation of a country’s image implemented through the means of cultural diplomacy, which also includes cultural propaganda, i.e. the promotion of a country using its culture as a tool. The methodological approach of the article is situated in the cultural and historical research field of music.

High-sensitivity cardiac SPECT system design with collimator-less interspaced mosaic-patterned scintillators.

Single-photon emission computed tomography (SPECT) is an important tool for myocardial perfusion imaging (MPI). Mechanical collimators cause the resolution-sensitivity trade-off in the existing cardiac SPECT systems, which hinders fast cardiac scan capability. In this work, we propose a novel collimator-less cardiac SPECT system with interspaced mosaic-patterned scintillators, aiming to significantly improve sensitivity and reduce scan time without trading-off image resolution. We propose to assemble a collimator-less cardiac SPECT with 7 mosaic-patterned detector modules forming a half-ring geometry. The detector module consists of 10 blocks, each of which is assembled with 768 sparsely distributed scintillators with a size of 1.68 mm × 1.68 mm × 20 mm, forming a mosaic pattern in the trans-axial direction. Each scintillator bar contains 5 GAGG(Ce) scintillators and 5 optical-guide elements, forming a mosaic pattern in the axial direction. In the Monte Carlo simulations, the in-plane resolution and axial resolution are evaluated using a hot-rod phantom and 5 disk phantoms, respectively. We simulate a cardiac phantom that is placed in a water-filled cylinder and evaluate the image performance with different data acquisition time. We perform image reconstruction with the expectation-maximization algorithm using system matrices derived from the simulation of a uniform cylindrical source filling the field-of-view (FOV). Besides, a 2-D prototype system is designed to demonstrate the feasibility of the collimator-less imaging concept. In the simulation system, the sensitivity is 16.31% ± 8.85% in a 180 mm (Φ) × 100 mm (L) FOV. The 6-mm rods in the hot rod phantom and the 5-mm disks in the disk phantom are clearly separable. Satisfactory MPI image quality is achieved in the cardiac phantom study with an acquisition time of 30 s. In prototype experiments, the point sources with an 8 mm center-to-center distance are clearly separable at different positions across the FOV. The study reveals a promising approach to high-sensitivity SPECT imaging without a heavy-metal collimator. In cardiac imaging, this approach opens the way to a very fast cardiac scan with good resolution. Further works are ongoing to build a practical 3-D imaging system based on the existing design.

Reconfigurable dipole receive array for dynamic parallel imaging at ultra-high magnetic field.

To extend the concept of 3D dynamic parallel imaging, we developed a prototype of an electronically reconfigurable dipole array that provides sensitivity alteration along the dipole length. We developed a radiofrequency array coil consisting of eight reconfigurable elevated-end dipole antennas. The receive sensitivity profile of each dipole can be electronically shifted toward one or the other end by electrical shortening or lengthening the dipole arms using positive-intrinsic-negative-diode lump-element switching units. Based on the results of electromagnetic simulations, we built the prototype and tested it at 9.4 T on phantom and healthy volunteer. A modified 3D SENSE reconstruction was used, and geometry factor (g-factor) calculations were performed to assess the new array coil. Electromagnetic simulations showed that the new array coil was capable of alteration of its receive sensitivity profile along the dipole length. Electromagnetic and g-factor simulations showed closely agreeing predictions when compared to the measurements. The new dynamically reconfigurable dipole array provided significant improvement in geometry factor compared to static dipoles. We obtained up to 220% improvement for 3 × 2 (Ry × Rz ) acceleration compared to the static configuration case in terms of maximum g-factor and up to 54% in terms of mean g-factor for the same acceleration. We presented an 8-element prototype of a novel electronically reconfigurable dipole receive array that permits rapid sensitivity modulations along the dipole axes. Applying dynamic sensitivity modulation during image acquisition emulates two virtual rows of receive elements along the z-direction, and therefore improves parallel imaging performance for 3D acquisitions.

Image and Word

Abstract The rapport between religion and film is not only historical but also ontological. The Abrahamic faiths specifically (Islam, Christianity, and Judaism) and the audio-visual medium of cinema share a complex affiliation with reference to two of their foundational elements: image and word. Building on the constitutive kernels of the Abrahamic religion of Islam (image and word), this paper will locate and define its formal manifestations in cinema; in other words, the way in which the conception of image and word at Islam marks film form. This endeavor will be sustained by calling upon some distinctive film cases of the so-called New Iranian Cinema. In particular, Offside (2006) and This Is Not a Film (2011) by Jafar Panahi, and Close-up (1990) by Abbas Kiarostami, as well as other films, will be utilized for analysis in order to delineate the qualities of the claimed religious film form in question. These films are selected as they foreground and thus play out the dialectic of image and word, their absence and their presence.

Репрезентация медиаобраза Китая в российской социальной сети (на материале постов о китайской популярной музыке и комментариев к ним)

The article reconstructs the media image of China based on social network discussions about Chinese pop music. As a new medium, social networks reflect the mutual socio-cultural interest of Russia and China. The author describes the concept of national media image in media linguistics and intercultural communication using China News. EKD, a public page in the VKontakte social network. The methods of media linguistics, cultural linguistics, axiology, and linguistic analysis helped to reveal the main themes in the image of China: musical genres; musicians and singers, their popularity in China and abroad; authors' opinions; commentators' opinions; non-verbal means. The research also revealed linguistic and non-linguistic means that establish Chinese pop music as part of the musical and performing arts. China appears as a country with a well-developed modern musical and performing culture, popular both in China and abroad.

1000× Faster Camera and Machine Vision with Ordinary Devices

In digital cameras, we find a major limitation: the image and video form inherited from a film camera obstructs it from capturing the rapidly changing photonic world. Here, we present vidar, a bit sequence array where each bit represents whether the accumulation of photons has reached a threshold, to record and reconstruct the scene radiance at any moment. By employing only consumer-level CMOS sensors and integrated circuits, we have developed a vidar camera that is 1,000x faster than conventional cameras. By treating vidar as spike trains in biological vision, we have further developed a spiking neural network-based machine vision system that combines the speed of the machine and the mechanism of biological vision, achieving high-speed object detection and tracking 1,000x faster than human vision. We demonstrate the utility of the vidar camera and the super vision system in an assistant referee and target pointing system. Our study is expected to fundamentally revolutionize the image and video concepts and related industries, including photography, movies, and visual media, and to unseal a new spiking neural network-enabled speed-free machine vision era.

Capturing ultra-broadband complex-fields of arbitrary duration using a real-time spectrogram

One of the most intuitive representations of a waveform is achieved through time-frequency analysis, which depicts how the frequency components of a wave evolve over time. Time-frequency representations, such as the spectrogram, are well-known for allowing full-field characterization of a signal in terms of amplitude and phase. However, present methods to capture the spectrogram of a waveform are only suited for either relatively slow (<GHz bandwidth) waveforms of arbitrary duration or fast (>THz bandwidth) waveforms of short duration. It remains very challenging to capture the time-frequency representation of broadband waves extending over long durations, as required for many important fields in science and technology. Here, we introduce a linear optics temporal imaging concept based on electro-optic time-lensing and dispersive propagation to map the 2D spectrogram as a 1D waveform along the temporal domain. This technique enables ultra-broadband spectrogram analysis without any gaps in the acquisition and with no inherent limitation on maximum signal duration. The spectrogram is captured at unmatched processing rates, up to 16 × 109 Fourier transforms per second (∼60 ps per spectral frame), using a single photodetector and in a fully self-referenced manner. Under certain conditions, we show how this method enables the single-shot full-field characterization of optical waveforms spanning multiple THz. The method is further showcased through accurate amplitude and phase recovery of high-speed complex-modulated optical telecommunication signals using direct intensity detection. This concept will enable the study of physical phenomena unreachable to date and disruptive advancements in high-speed communications, sensing, and information processing.

Balloon flight demonstration of coronagraph focal plane wavefront correction with PICTURE-C

The Planetary Imaging Concept Testbed Using a Recoverable Experiment - Coronagraph (PICTURE-C) mission is designed to directly image debris disks and exozodiacal dust around nearby stars from a high-altitude balloon using a 60 cm diameter off-axis telescope and a vector vortex coronagraph. During its second flight from Fort Sumner, New Mexico, on September 28, 2022, PICTURE-C successfully used its high and low-order wavefront control systems to perform focal plane wavefront correction for the first time on an observatory in a near-space environment. The coronagraph achieved a modest broadband (20%) contrast of 5 × 10 − 6, with performance limited by dynamic pointing transients. The low-order wavefront control system achieved optical pointing stabilization of 1 milliarcseconds (mas) root mean squared (RMS) over 30 second timescales.

Soft shadow images

In traditional optics education, shadows are often regarded as a mere triviality, namely as silhouettes of obstacles to the propagation of light. However, by examining a series of shadow phenomena from an embedded perspective, we challenge this view and demonstrate how in general both the shape of the object and light source have significant impact on the resulting soft shadow images. Through experimental and mathematical analysis of the imaging properties of inverse objects, we develop a generalized concept of shadow images as complementary phenomena. Shadow images are instructive examples of optical convolution and provide an opportunity to learn about the power of embedded perspective for the study of optical phenomena in the classroom. Additionally, we introduce the less-known phenomenon of the bright shadow.

In order to achieve the research objectives, job satisfaction and body image scales were constructed and prepared by following the steps and procedures for constructing and preparing psychological scales and processing their data with the statistical bag for social sciences (SPSS). The study came to several conclusions, including The higher the job satisfaction of physical training teachers, the more positive body image there is. Among the most important recommendations that the researcher intends to consider is: paying attention to the concept of body image as perceived by society in particular, due to the importance of that for physical training instructors at the Iraqi Police College.

Phase-based vibration imaging for structural dynamics applications: Marker-free full-field displacement measurements with confidence measures

Inspired by the concept of thermal imaging, we develop a phase-based vibration imaging technique using marker-free full-field displacement measurements, which aims to determine vibrational energy distribution and possibly vibration parameters as the thermal imaging determining thermal energy distribution using colormap. In this study, accurate full-field measurements are conducted at the sub-pixel level by performing a full-field phase-based optical flow with three novel progresses. First, an image-preprocessing Gaussian smoothing gradient is applied to reduce the nonlinear phase caused by homogenous patterns and image noise. Second, two confidence measures (phase nonlinearity and filter response) are adopted to obtain reliable displacement measurements estimated from the multi-scale and multi-direction phases. Third, the combination of vector average and the intersection of constraints ensure the accuracy of integrating every pixel’s displacement components. The vibrations can then be imaged by analyzing the acquired full-field displacements using techniques such as mean absolute deviation and frequency analyses. The capability of the proposed technique is demonstrated through numerical experiments using artificial patterns. After then, experimental validation is performed, which includes full-field operational deflection shape extraction on a 5-story structure and vibration imaging of an in-service hydrogen charging station, further proving the effectiveness of the proposed vibration imaging technique.

Body image assessment of fitness centers´ members & behavioral intentions: can we actually achieve members´ retention?

The concept of body image is multidimensional and concerns the attitude of each person towards their body and their appearance. The aim of this research was to study how Greek fitness center members evaluate their body image, and whether this evaluation is differentiated in terms of gender, age and BMI. Moreover, the study aimed to survey whether fitness center members’ body image may predict their intention to maintain their fitness center membership. The research sample consisted of 220 adult members of fitness centers in a Greek city. For the needs of this research, the MBSRQ-Appearance scale was used (Cash, 2000), including 4 factors: i) satisfaction with appearance (7 items), ii) investment in appearance (12 items) iii) anxiety with appearance and weight (4 items) iv) weight self-categorization (2 items) and v) satisfaction with body parts (9 items). The MBSRQ has been previously adapted to a Greek population with satisfactory validity results. For the intention to continue participating in a fitness center, one question based on the Theory of Planned Behavior was used: I will use the fitness center services again next year. All responses were given on a five-point Likert scale. For the needs of this research, the questionnaire gathered additional demographic characteristics of the sample’s gender, age and Body Mass Index (BMI). No statistical differences of the body image evaluation occurred depending on the sample’s sex and age. Instead, differences emerged in the way members of the sample perceived their body image, and more specifically their “Self-categorization of weight” depending on whether they were classified as "normal" based on their BMI, "overweight" or "obese". As for the intention to continue their membership, it may be predicted by the Satisfaction with body parts factor. Attracting clients to fitness services should stop focusing on promoting a fit and flawless body, encouraging people who underestimate their body image to take advantage of their services. Key Words: fitness centers, body image, customer intentions, fitness center members

A hybrid multi-particle approach to range assessment-based treatment verification in particle therapy

Particle therapy (PT) used for cancer treatment can spare healthy tissue and reduce treatment toxicity. However, full exploitation of the dosimetric advantages of PT is not yet possible due to range uncertainties, warranting development of range-monitoring techniques. This study proposes a novel range-monitoring technique introducing the yet unexplored concept of simultaneous detection and imaging of fast neutrons and prompt-gamma rays produced in beam-tissue interactions. A quasi-monolithic organic detector array is proposed, and its feasibility for detecting range shifts in the context of proton therapy is explored through Monte Carlo simulations of realistic patient models and detector resolution effects. The results indicate that range shifts of {1},hbox {mm} can be detected at relatively low proton intensities (22.30(13)times 10^{7} protons/spot) when spatial information obtained through imaging of both particle species are used simultaneously. This study lays the foundation for multi-particle detection and imaging systems in the context of range verification in PT.

Projective Imagination: Vilém Flusser’s Concept of the Technical Image

The article discusses the technical image, a central concept in Vilém Flusser’s later main work Into the Universe of Technical Images (1985a). After identifying its various dimensions, the analysis frames the concept as an amalgamation of disciplines, theories, and artistic practices the cultural philosopher Flusser explored during the 1960s and especially the 1970s. In particular, the field of information aesthetics developed by Max Bense and Abraham A. Moles, among others, as well as artistic video practices in France and the United States played an important role in both Flusser’s biography and the formation of his technical image concept. At the same time, in Flusser’s cultural philosophy the technical image is the condition and result of a new kind of human imagination, which in this paper is specified as ‘projective imagination’.

Student learning of head and neck anatomy using cone beam computed tomography and immersive virtual reality.

The purpose of this study was to evaluate the efficacy of student learning of anatomy and 3D imaging concepts using cone beam computed tomography (CBCT) and immersive virtual reality (VR) technology. Ninety (n=90) first year dental students with no previous experience in 3D imaging were recruited. All participants completed a 10-item, multiple-choice questionnaire (MCQ) and a pre-survey prior to the educational intervention. Following a brief video orientation on CBCT and anatomy, each participant underwent a one-on-one educational intervention using immersive VR with calibrated instructors to identify head and neck anatomic structures using a VR/CBCT educational tool. Immediately following the intervention, all participants completed a postsurvey, a second MCQ, NASA task load index and presence questionnaires. Participants completed a third MCQ 2 weeks following the intervention. Analysis of objective measures of performance on MCQ's (p<0.05) and subjective data from the questionnaires was completed. The students doubled their mean test scores 2.45±1.274 to 5.99±1.576 on MCQ's immediately following the educational intervention (p<0.05). The significant increase in the MCQ test scores was maintained after 2weeks, 5.73±1.721 (p<0.05). There were no gender differences in student test performance. Students rated the immersive VR/CBCT educational intervention experience highly for control, sensory, and realism factors with minimal distraction and frustration factors. Results from this study show that immersive VR/CBCT educational intervention improved test performance and contributed to information recall in students. Further benefits reported by participants include the sense of presence and increased engagement using immersive VR.

Genital body image education in young adolescent girls: A proof of concept pilot study

Our research team previously developed a brief educational video aimed at increasing adolescent girls’ knowledge of the variation in cisgender female genital appearance and improving attitudes towards genital appearance. This video was efficacious with 16–18-year-old girls, but their feedback suggested that younger girls may gain greater benefit. Owing to the younger age group and sensitivity of the topic, we undertook a small pilot study, using a mixed methods approach (quantitative followed by qualitative study phase), to explore the understanding of 13–15-year-old girls of their genital anatomy and body image, and their impressions of the video. The sample (N = 6) showed, on average, low-to-moderate levels of genital anatomical knowledge and genital appearance satisfaction. In qualitative interviews, thematic analysis showed girls had received limited genital-related sexual education and had not considered genitals to be part of their concept of body image. However, after watching the video, they reported an appreciation of the diversity in genital appearance and encouraged use of the video in schools to prompt discussions about genital body image. There are broader implications of this research, namely, that the education of girls about the diversity in genital appearance could be important in improving their future gynaecological and sexual well-being.
