The original data of one view video is huge and that of multi-view video is much more. So, data compression is important for multi-views, and data compression is a key technology for multi-views. In this paper, we explore an efficient fractal video codec with multi-views. From the experimental results with the proposed method and other state of the art methods, we can conclude that the proposed algorithm for multi-view coding is robust, and provides less encoding time and high compression ratio while maintaining good compression quality.

This paper presents a safety estimation methodology for soft landing explorations on the Moon. In our application we use digital elevation models (DEM) of given lunar terrain extracted from on-board lidars. Currently most landing safety analysis methods are based on topographical analysis which needs quite a lot of computation. Here we adopt a Monte-Carlo simulation method which doesn't need to identify complex lunar topographical characteristics and needs less computation. After developing lunar lander's collision detection model, lander gradient model, and lander aspect model, Monte-Carlo simulations of landing on given DEM are conducted iteratively. Safety estimation is implemented by analyzing corresponding simulation results using statistical analysis method. Simulation errors of this algorithm are also deduced and analyzed in this paper. Computer simulation results show that this method can provide valuable information to estimate landing safety of given terrain for lunar soft landing missions.

For microwave staring correlated imaging method, high-precision requirement of time synchronization between stochastic radiation fields and scattered echo signals must be satisfied. In order to reduce its influence on microwave correlated imaging results, a novel microwave staring correlated imaging scheme is proposed based on short-time integral stochastic radiation fields. Then the short-time integral correlated imaging model on the intra-pulse stochastic radiation fields and intra-pulse scattered echoes is established, which improve its tolerance capability of time synchronization error of the imaging system, meanwhile, the temporal-spatial stochastic characteristics of short-time integral radiation field can be maintained as well as its super-resolution potential of microwave correlated imaging. Finally, the effectiveness of this imaging method is validated by the numerical simulations.

In ophthalmology, Hess screen is an imperative instrument which is primarily employed for the measurement of paralytic strabismus. Strabismus is the state of eye in which eyes are not properly aligned with each other and patient complaint for double vision (diplopia). In this paper we propose a model for the automation of traditional Hess Screen instrument for the diagnosis of strabismus. Currently this system is totally manual in operate and consume lot of time of patient as well as ophthalmologist. We present a three stage system consisting of image acquisition, point extraction, plotting and computer aided diagnosis algorithm. First stage is composed of a digital camera which will take images of the HESS board and transfer it to a computer. In second stage image processing techniques are used to extract points from images to draw HESS plot, and in third stage an algorithm based on fuzzy logic is designed which will automatically diagnose the paralytic strabismus using statistics of the Hess graphs. This system is convenient, fast and has an ability to manage medical record with refinement. The evaluation of proposed system is performed by using dataset provided by well known local hospital.

Electronic portal mega-electronvolt (MV) monitoring for radiation therapy is very important for tumor localization. Furthermore, in the latest systems, before the radiation treatment, the patient is also positioned on the treatment bed with a flat-panel detector (FPD) based kilo-electronvolt (kV) CT scan for better soft tissue visibility. In the article we prove by measurement and imaging that a regular Cu-GOS scintillator combination on an a-Si TFT + photodiode FPD can work in reverse direction with the same efficiency as in forward direction at high energy (MV) imaging. More importantly, in reverse mode it can be used also as a kV imager because the Cu plate, which contributes towards improved imaging at MV energy, does not block the kV X-ray beams in this direction. So we can have a universal MV-kV imager integrated into one.
电子门静脉巨电子伏特(MV)监测是放射治疗肿瘤定位的重要手段。此外，在最新的系统中，在放射治疗之前，患者也被安置在治疗床上，使用平板探测器(FPD)进行千电子伏(kV) CT扫描，以获得更好的软组织可见性。在本文中，我们通过测量和成像证明了一个规则的Cu-GOS闪烁体组合在a- si TFT +光电二极管FPD上可以在高能量(MV)成像时以与正方向相同的效率反向工作。更重要的是，在反向模式下，它也可以用作千伏成像仪，因为铜板有助于提高毫伏能量下的成像，不会阻挡这个方向的千伏x射线束。所以我们可以有一个通用的MV-kV成像仪集成到一个。

Layover and shadow are ubiquitous phenomenon in SAR images. The singularity of phase in layover and shadow areas leads to severe difficulties for phase unwrapping and makes it hard to derive the height information of the target. Therefore they should be detected and dealt with. In this paper, an improvement is made to the classic eigenvalue decomposition method of layover and shadow detection, and a novel method based on the improved eigenvalue decomposition method, amplitude segmentation and the local frequency estimation is proposed to detect layover and shadow for InSAR images. The validity of the method proposed in this paper is testified by simulation.

In this paper, the data aggregation approach is proposed to support the computer-aided detection of pathological changes in coronary arteries structure. Unlike the previous papers the authors mainly focused on the possibilities of utilization of data aggregation techniques to assess the degree of threat to the patient's health depending on the type of distribution of coronary arteries (balanced artery distribution, right dominant artery distribution or left dominant artery distribution). Moreover, in order to determine the appropriate projection for further analysis from the set of image data the authors proposed two heuristics: based on the Feret diameter and based on the center of gravity. Presented techniques can support a comprehensive description of the analyzed image by identifying the most important parameters of a given structure, and then analyzing their meaning by aggregating information obtained from two sources: (1) the topology of coronary arteries (their mutual spatial relations), and (2) the analysis of individual arteries of the coronary arteries system. The obtained results are very promising - for the image data included in the experiment around 82% of recognitions were correct.

The objective of this study is the discrimination and characterization of different lung cancer monoline cells using statistical analysis of polarimetric backscattered signals. The main aspect of this study is the use of the Welch's t-test and the p-value statistics as a representative metric for discriminating distributions based on their mean and standard deviation. The outcome of this study indicates that enhanced discrimination of lung cancer samples can be obtained based on their t-test values between different cancer samples for different geometries.

The computation of relaxation time from quantitative magnetic resonance (MR) imaging depends on the applied algorithms. The purpose of this project was to use the algebraic curve fitting algorithm to quantify T2 mapping of knee articular cartilage for T2 relaxation time calculation. The T2 images of a healthy male volunteer's right knee tibiofemoral joint cartilage were generated by a 3T MR imaging scanner using a spin echo multislice multiecho (MSME) Carr-Purcell Meiboom-Gill (CPMG) sequence. The medial and lateral condyle cartilage regions were further subdivided into three compartments - anterior, middle and posterior for identifying T2 values variation in between them. The T2 relaxation time mean and standard deviation in each region of interest (ROI) was calculated using the algebraic fitting algorithm and compared with conventional nonlinear algorithms. The results show that the algebraic fitting algorithm is feasible for T2 relaxation time calculation of knee tibiofemoral condyle cartilage. It is not only clear but also sensitive to T2 MR imaging of knee articular cartilage.

Based on the shape adaptive discrete cosine transform (SA-DCT) and its application in image coding, this paper proposes a new image coding algorithm based on image segmentation and shape adaptive all phase biorthogonal transform (SA-APBT). In this paper, an image is divided into two parts, the region-of-interest (ROI) and the background area, which can be encoded separately. Intra macroblocks (all pixels are located in ROI or background region) are processed with APBT; while marginal macroblocks (part of pixels are located in ROI) are processed with SA-APBT. Experimental results are obtained with the test images. It can be concluded that the coding performance of the proposed algorithm is better than that of conventional algorithms. Both the objective quality and subjective effect are improved.
