作者： Eric Fontaine Hsien-Hsin S. Lee School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA

The Katsevich image reconstruction algorithm is the first theoretically exact cone beam image reconstruction algorithm for a helical scanning path in computed tomography (CT). However, it requires much more computation and memory than other CT algorithms. Fortunately, there are many opportunities for coarse-grained parallelism using multiple threads and fine-grained parallelism using SIMD units that can be exploited by emerging multi- core processors. In this paper, we implemented and optimized Katsevich image reconstruction based on the previously proposed pi- interval method and cone beam cover method and parallelized them using OpenMP API and SIMD instructions. We also exploited symmetry in the backprojection stage. Our results show that reconstructing a 1024 times 1024 times 1024 image using 5120 512 times 128 projections on a dual-socket quad-core system took 23,798 seconds on our baseline and 642 seconds on our final version, a more than 37 times speedup. Furthermore, by parallelizing the code with more threads we found that the scalability is eventually hinged by the limited front-side bus bandwidth.

International Symposium on parallel and distributed processing (IPDPS)

作者： Basile Schaeli Sebastian Gerlach Roger D. Hersch School of Computer and Communication Sciences Ecole Polytechnique Fédéale de Lausanne Switzerland

In message-passing parallel applications, messages are not delivered in a strict order. In most applications, the computation results and the set of messages produced during the execution should be the same for all distinct orderings of messages delivery. Finding an ordering that produces a different outcome then reveals a message race. Assuming that the partial order execution graph (POEG) capturing the causality between events is known for a reference execution, the present paper describes techniques for identifying independent sets of messages and within each set equivalent message orderings. Orderings of messages belonging to different sets may then be re-executed independently from each other, thereby reducing the number of orderings that must be tested to detect message races. We integrated the presented techniques into the dynamic parallel schedules parallelization framework, and applied our approach on an image processing, a linear algebra, and a neighborhood-dependent parallel computation. In all cases, the number of possible orderings is reduced by several orders of magnitudes. In order to further reduce this number, we describe an algorithm that generates a subset of orderings that are likely to reveal existing message races.

A tristate approach (TA) for image denoising processing is presented; the noise is aimed at the presence of pepper-and-salt noise. The newness of this method is that it develops a new route in the field of image restoration. The tristate approach algorithm focuses on the removal and restoration of the noisy speckles and avoids blurring and averaging edges and non-noise pixels in a way different from other known algorithms. Any noisy pixel is replaced by an estimated value. This value is the weighted mean of the pixels neighboring to the noisy pixel or the four iteration pixels got before it. This paper describes, analyzes and compares several methods and results of removing noise from an image. We have performed the experiments by adding Salt-and-Pepper in an original image.

image segment is one of the most fundamental and difficult problems in image analysis and computer vision. The image thresholding problem is treated as an important issue in image processing, and it can not only reduce the image data, but also lay a good foundation for succedent target recognition and image understanding. Character of global thresholding segmentation and local thresholding was analyzed in image segmentation. A new thresholding statistic iterative arithmetic is presented to overcome the direct worth method in thresholding, aiming at some lighting asymmetry and the abrupt a blemish for, or bigger arithmetic figure in ratio in a variety in gray of background image. Statistics iterative thresholding segmentation, based on image gray histogram and Gauss statistics distributing, obtain the theory expression of statistics iterative method and the best worth thresholding method and steps. Aviation image was thresholding segmentation using statistic iterative arithmetic, histogram technique and adaptive method respectively. Compared three thresholding results, it shows that statistic iterative method greatly improved the anti-noise capability of image segmentation and had the good result to the image of the worth and not easy to segment in full value thresholding method.

Breast cancer, with the exception of lung cancer, is the leading cause of cancer deaths in women. It is also one of the few cancers that can be controlled by using asymptomatic screening method, followed by effective treatments. One recent screening modality under development, microwave tomography, uses the apparent dielectric property contrasts between different breast tissues at microwave frequencies. Microwave tomography uses a numerical model and the image reconstruction consists of iteratively searching the breast structures, applying the numerical model to the breast structures, and matching measured data with computation results of the model. This paper focuses on finite-difference time-domain (FDTD) for the numerical model and genetic algorithm (GA) for the iterative searches. FDTD and GA are time-consuming, yet they are data parallel in nature. In this paper, a parallel algorithm integrating GA and FDTD for detecting tumors using microwave tomography technique is presented. The algorithm is implemented on distributed memory machines using MPI.

Region-based image Fusion by Using Region Priorities

Region-based Image Fusion by Using Region Priorities

ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and parallel/distributed Computing (SNPD)

作者： Zhang Yingjie Ge Liling School of Mechanical Engineering Xi''an Jiaotong University Xi'an Shaanxi China School of Mechanical Engineering Xi''an University of Technology Xi'an Shaanxi China

In this paper, a new region-based approach to multi-resolution image fusion is presented. To make fusion decision better, a master image is selected from the source images. Then, it is segmented using the background subtraction based Mumford and Shah algorithm, which significantly improves the segmentation at quality and convergence speed. After that, the fusion rules on every region of the image are determined based on the best priority-first strategy. Moreover, the fusion on the whole image domain is replaced by using different rules on every segmented region of the image. The corresponding regions in other images are located by linear mapping methods. Some numerical results have been given and compared to the pixel-based fusion methods. Despite an increase in complexity, more intelligent fusion rules may be applied to remove side effects like reducing contrast and sensitive to error of registration.

We present a survey of modern parallel MATLAB techniques. We concentrate on the most promising and well supported techniques with an emphasis in SIP applications. Some of these methods require writing explicit code to perform inter-processor communication while others hide the complexities of communication and computation by using higher level programming interfaces. We cover each approach with special emphasis given to performance and productivity issues.

International Symposium on parallel and distributed processing (IPDPS)

作者： M. Lozano J. M. Orduna V. Cavero Departamento de Informática Universidad de Valencia Valencia Spain

Last years have witnessed how crowd simulations have become an essential tool for many virtual environment applications. These applications require both rendering visually plausible images and managing the behavior of autonomous agents, and therefore they need a scalable design that allows them to simultaneously tackle these two requirements. One of the main problems in the design of a scalable crowd simulation consists of efficiently distributing among different computers the semantic database containing the virtual world. In this paper, we propose a genetic approach for distributing the semantic database of crowd simulations in such a way that the dependencies among the computers hosting the pieces of the database are minimized. The proposed approach avoids the saturation of these computers by ensuring that the size of the pieces assigned to each computer is properly balanced. The performance evaluation results show that the proposed approach significantly reduces the resulting overhead in regard to other local search methods, regardless of the movement pattern of the agents. Therefore, it allows an effective partition of the semantic database.

IEEE International Conference on image processing

作者： Shyi-Chyi Cheng Wei-Kan Huang Yu-Jhih Liao Da-Chun Wu Department of Computer Science and Engineering National Taiwan Ocean University Taiwan Department of Computer and Communication Engineering National Kaohsiung First University of Science and Technology Taiwan

This paper proposes a parallel solution to retrieve images from distributed data sources using perceptual grouping of block-based visual patterns. The method of grouping visual patterns into image model based on generalized Hough transform is one of the most powerful techniques for image analysis. However, real-time applications of this method have been prohibited due to the computational intensity in similarity searching from a large centralized image collection. A query object is decomposed into non-overlapped blocks, where each of them is represented as a visual pattern obtained by detecting the line edge from the block using the moment-preserving edge detector. A voting scheme based on generalized Hough transform is proposed to provide object search method, which is invariant to the translation, rotation, scaling of image data. In this work, we describe a heterogeneous cluster-oriented CBIR implementation. First, the workload to perform an object search is analyzed, and then, a new load balancing algorithm for the CBIR system is presented. Simulation results show that the proposed method gives good performance and spans a new way to design a cost-effective CBIR system.

Conference on Computer Vision and Pattern Recognition (CVPR)

作者： Changsong Shen Sidney S. Fels James J. Little Department of Electrical and Computer Engineering University of British Columbia Canada Department of Computer Science University of British Columbia Canada

This paper presents our progress on OpenVL -a novel software architecture to address efficiency through facilitating hardware acceleration, reusability and scalability for computer vision. A logical image understanding pipeline is introduced to allow parallel processing. As well, we discuss our middleware -VLUT that enables applications to operate transparently over a heterogeneous collection of hardware implementations. OpenVL works as a state machine, with an event-driven mechanism to provide users with application-level interaction. Various explicit or implicit synchronization and communication methods are supported among distributed processes in the logical pipelines. The intent of OpenVL is to allow users to quickly and easily recover useful information from multiple scenes across various software environments and hardware platforms. We implement two different human tracking systems to validate the critical underlying concepts of OpenVL.
