AN IMPROVED METHOD OF AGM FOR HIGH PRECISION GEOLOCATION OF SAR IMAGES

Abstract. In order to take full advantage of SAR images, it is necessary to obtain the high precision location of the image. During the geometric correction process of images, to ensure the accuracy of image geometric correction and extract the effective mapping information from the images, precise image geolocation is important. This paper presents an improved analytical geolocation method (IAGM) that determine the high precision geolocation of each pixel in a digital SAR image. This method is based on analytical geolocation method (AGM) proposed by X. K. Yuan aiming at realizing the solution of RD model. Tests will be conducted using RADARSAT-2 SAR image. Comparing the predicted feature geolocation with the position as determined by high precision orthophoto, results indicate an accuracy of 50m is attainable with this method. Error sources will be analyzed and some recommendations about improving image location accuracy in future spaceborne SAR's will be given.

AN IMPROVED IMAGE MATCHING METHOD BASED ON SURF ALGORITHM

Abstract. Many state-of-the-art image matching methods, based on the feature matching, have been widely studied in the remote sensing field. These methods of feature matching which get highly operating efficiency, have a disadvantage of low accuracy and robustness. This paper proposes an improved image matching method which based on the SURF algorithm. The proposed method introduces color invariant transformation, information entropy theory and a series of constraint conditions to increase feature points detection and matching accuracy. First, the model of color invariant transformation is introduced for two matching images aiming at obtaining more color information during the matching process and information entropy theory is used to obtain the most information of two matching images. Then SURF algorithm is applied to detect and describe points from the images. Finally, constraint conditions which including Delaunay triangulation construction, similarity function and projective invariant are employed to eliminate the mismatches so as to improve matching precision. The proposed method has been validated on the remote sensing images and the result benefits from its high precision and robustness.

AN IMPROVED BOX-COUNTING METHOD TO ESTIMATE FRACTAL DIMENSION OF IMAGES

Fractal dimension (FD) reflects the intrinsic self-similarity of an image and can be used in image classification, image segmentation and texture analysis. The differential box-counting (DBC) method is a common approach to calculating the FD values. This paper proposes an improved DBC-based approach to optimizing the performance of the method in the following ways:reducing fitting errors by decreasing step lengths, considering under-counting boxes on the border of two neighboring box-blocks and making better use of all the pixels in the blocks while not neglecting the middle parts. The experimental results show that the fitting error of the new method can be decreased to 0.012879. The average distance of the FD values is decreased by 16.0% in the divided images and the average variance of the FD values is decreased by 30% in the scaled images, compared with other modified methods. The results show that the new method has a better performance in the recognition of the same type of images and the scaled images.

BI-PHASE BOX COUNTING: AN IMPROVED METHOD FOR FRACTAL ANALYSIS OF BINARY IMAGES

Many natural systems are irregular and/or fragmented, and have been interpreted to be fractal. An important parameter needed for modeling such systems is the fractal dimension, D. This parameter is often estimated from binary images using the box-counting method. However, it is not always apparent which fractal model is the most appropriate. This has led some researchers to report different D values for different phases of an analyzed image, which is mathematically untenable. This paper introduces a new method for discriminating between mass fractal, pore fractal, and Euclidean scaling in images that display apparent two-phase fractal behavior when analyzed using the traditional method. The new method, coined "bi-phase box counting", involves box-counting the selected phase and its complement, fitting both datasets conjointly to fractal and/or Euclidean scaling relations, and examining the errors from the resulting regression analyses. Use of the proposed technique was demonstrated on binary images of deterministic and stochastic fractals with known D values. Traditional box counting was unable to differentiate between the fractal and Euclidean phases in these images. In contrast, bi-phase box counting unmistakably identified the fractal phase and correctly estimated its D value. The new method was also applied to three binary images of soil thin sections. The results indicated that two of the soils were pore-fractals, while the other was a mass fractal. This outcome contrasted with the traditional box counting method which suggested that all three soils were mass fractals. Reclassification has important implications for modeling soil structure since different fractal models have different scaling relations. Overall, bi-phase box counting represents an improvement over the traditional method. It can identify the fractal phase and it provides statistical justification for this choice.

Localised inhibition of microrna-15 and -16 results in an improved angiogenic recovery following limb ischaemia

s / International Journal of Surgery 12 (2014) S13eS117 S15 assessors (1 surgery, 1 pathology). Survival was analyzed using KaplaneMeier curves and the Log-rank test. Results: There is increased tumour epithelial cytoplasmic staining for NR4A2, and an altered nuclear-cytoplasmic ratio with more cytoplasmic NR4A2 in tumour compared to matched normal tissue (p 1⁄4 0.001). High tumour cytoplasmic NR4A2 is associated with a significantly worse overall and disease specific survival in colorectal cancer. (5-year DSS 64% high cytoplasmic NR4A2 versus 80% low cytoplasmic NR4A2, log-rank test p1⁄40.049, 5-year OS p1⁄40.003) Conclusions: There is marked cytoplasmic mislocalisation of NR4A2 in colon cancer. High tumour cytoplasmic NR4A2 is associated with an adverse prognosis. 0921: LOCALISED INHIBITION OF MICRORNA-15 AND -16 RESULTS IN AN IMPROVED ANGIOGENIC RECOVERY FOLLOWING LIMB ISCHAEMIA Saran Shantikumar, Lynsey Howard, Micol Marchetti, Marco Meloni, Costanza Emanueli.

Mitomycin C guidelines: An improvement in department adherence through the process of audit, led by junior doctors

s / International Journal of Surgery 12 (2014) S13eS117 S104 0328: MITOMYCIN C GUIDELINES: AN IMPROVEMENT IN DEPARTMENT ADHERENCE THROUGH THE PROCESS OF AUDIT, LED BY JUNIOR DOCTORS Gerard Walls , David Curry, Hugh O'Kane. Regional Urology Unit, Belfast City Hospital, Northern Ireland, UK. Introduction: The authors intended to establish adherence to guidelines regarding time to administration of intravesical chemotherapy postTURBT, in the Regional Urology Unit. EORTC recommends Mitomycin C (MMC) instillation within 6 hours in eligible patients this reduces recurrence rates by 39%. Methods: Prospective audit of time to administration in all eligible patients during a 3 month period. Results were discussed at departmental level with a three tiered approach to improvement. Primarily, initiation of in-theatre instillation (Mostafid et al). Second, a training programme for ward staff in handling cytotoxic agents. Finally, awareness of the problem was raised to trainee urologists at the Regional Audit Meeting. A repeat three month audit series was performed six months later. The latter two processes had been implemented with plans for in-theatre administration on-going. Results: Initially, in 19 patients (40 eligible) the mean time to MMC administration was 18.3hrs (2.3-28.2hrs). 15.7% patients received MMC 3mm, first time. Unanimous, unequivocal histopathological diagnoses were achieved. Conclusions: Few biopsy devices provide satisfactory, representative and consistent samples for diagnosis. We experienced an unpredictable outcome with a 25% re-biopsy rate with various devices, however with BIGopsy forceps accurate histopathological diagnoses were achieved with a significant impact on the timely treatment for urothelial malignancies. 0401: HOW CLINICAL AUDIT HAS LED TO REDUCED RATES OF POST TRUS BIOPSY SEPSIS IN OUR TRUST Nicholas Gill , Michael Onyema, Anne Dyas, Vincent Koo, Paul Rajjayabun. Alexandra Hospital, Redditch, UK. Introduction: We recently reported the findings of a regional audit which identified rates of sepsis increasing to 1.8% following transrectal ultrasound guided prostate biopsies (TRUS). Following this audit I.V. Gentamicin 160mg was introduced as additional prophylaxis for patients undergoing TRUS biopsy. Our aim was to assess the impact of adding Gentamicin to the TRUS antibiotic prophylaxis bundle since implementation in August 2013. Methods: Analysis of all patients who underwent TRUS biopsy across our Trust between August-December 2013 with minimum 1-month follow up. Our findings were compared against our previous audit data and published literature. Results: Therewere 246 TRUS biopsy procedures carried out across the Trust following the introduction of our new antibiotic prophylaxis regime. Median age of the population examined was 67 years (range 42-84). Only 1 patient was admitted to Secondary care with significant sepsis (0.4%), 3 patients had positive urine cultures performed inPrimarycare but didnot require hospital admission (1.2%). There were no ITU admissions or mortalities. Conclusion: We conclude that the addition of I.V. Gentamicin has dramatically reduced the incidence of significant sepsis post-TRUS biopsy. This is an example of howwe have utilised audit tomodify clinical practice for the benefit of our patients. 0403: PROGNOSIS FOLLOWING PERCUTANEOUS NEPHROSTOMY INSERTION FOR MALIGNANT OBSTRUCTIVE UROPATHY: ONE CENTRE'S EXPERIENCE Nicholas Gill , Kevin Williams, Phil Holland, Chris Phillips, Fabio Conti, K.

O6.06 * PERIPHERAL T CELL RESPONSES IN GLIOBLASTOMA PATIENTS ARE ASSOCIATED WITH AN IMPROVED SURVIVAL

BACKGROUND: Spontaneous anti-tumor T cell responses have been detected in several tumor types. However, not only in glioblastoma it is unclear if such immune responses influence patient outcome. MATERIAL AND METHODS: To detect such immune responses, occurence and frequencies of memory T-cells were determined in the peripheral blood of GBM patients applying the IFN gamma ELISPOT assay and using corresponding tumor lysates (n = 106) or a set of immunogenic polypeptides (n = 32). Extent of resection was assessed by either intraoperative or early postoperative MRI. In addition, intratumoral infiltration of different T-cell subpopulations at the time of first diagnosis was analyzed by immunohistochemistry (n = 20) and compared to the occurrence of spontaneous immune responses. RESULTS: T-cell responses against autologous tumor lysate were detected in 61/106 patients. Subsequent survival analysis concentrating on IDH1wt glioblastoma revealed a significant difference towards an improved survival for patients with a spontaneous immune response (p = 0.0251). Most interestingly, when stratifying for the extent of surgery those patients, who received a complete tumor resection and showed a spontaneous T cell response, survived significantly longer (p = 0.0002). In contrast, in subtotally resected patients the immune response did not improve survival. In line with these observations, occurrence of memory T cell responses against a set of known GBM-associated antigens (TTR, MAGE A3, S100A9) also trended to a better survival in those GBM patients who responded to all three antigens. Finally, increased frequency of intratumoral T cell infiltrates was also associated with the occurrence of spontaneous immune responses and an improved survival. CONCLUSIONS: The present analysis for the first time depicts on several levels a significant influence of the patient's immune system on the course of the disease in GBM patients. In this regard the most crucial prerequisite seems to be the MRI-based complete tumor resection. Most likely surgical removal of the immunosuppressive tumor environment allows for the beneficial reactivation of pre-existing immune responses.

AN IMPROVED GENETIC ALGORITHM AND ITS APPLICATION TO CRACK EXAMINATION

In this paper, a rail crack examination method based on an optimized complex evolutionary algorithm is proposed. The proposed approach has overcome the problems in which the fault diagnosis of wavelet packet decomposition is easily influenced by environmental factors, and the traditional genetic algorithm has a slow convergence speed and is prone to prematurity. In current method, to control the convergence performance, the diversity probability Pg is added in the update operation. According to the characteristics of rail crack fault signal, optimization function and cost function which consider the information in time and frequency domains are constructed and the information extraction is effectively realized. From field testing, the obtained results demonstrate that the present crack fault examination algorithm has higher accuracy rate, faster convergence rate and good stability. The present research work not only make up for the deficiency of traditional algorithm, but also provides a new examination method for wheel and rail noise fault diagnosis.
