IEEE International conference on parallel and distributed Computing, Applications and Technologies (PDCAT)

作者： Louis Gesbert Zhenjiang Hu Frederic Loulergue Kiminori Matsuzaki Julien Tesson MLstate Paris France National Institute of Information Tokyo Japan LIFO Université d''Oran-Es-senia France Kochi University of Technology Kochi Japan

With the current generalisation of parallel architectures arises the concern of applying formal methods to parallelism. The complexity of parallel, compared to sequential, programs makes them more error-prone and difficult to verify. Bulk Synchronous parallelism (BSP) is a model of computation which offers a high degree of abstraction like PRAM models but yet a realistic cost model based on a structured parallelism. We propose a framework for refining a sequential specification toward a functional BSP program, the whole process being done with the help of the Coq proof assistant. To do so we define BH, a new homomorphic skeleton, which captures the essence of BSP computation in an algorithmic level, and also serves as a bridge in mapping from high level specification to low level BSP parallel programs.

conference on Medical Imaging - Physics of Medical Imaging

A generalized approach to describing transfer of signal and noise (MTF and NPS) through medical imaging systems has been developed over the past several years in which image-forming processes are represented in terms of serial and parallel cascades of amplified point processes. We use the techniques of both cascaded systems analysis and stochastic point process theory to develop fundamental limitations of system performance for energy-discriminating single photon counting (SPC) x-ray imaging detectors to assist in the optimal design of new systems. Using this approach, the mean and variance of photon-energy determinations for a simple model of a hypothetical flat-panel x-ray imaging detector are calculated. It is shown that energy imprecision is ultimately determined by the number of secondary quanta collected by the detector. Successful designs will likely have small work-function values and/or high collection efficiencies as well as adaptive binning strategies to collect all secondary quanta liberated for each x-ray interaction. K-escape, responsible for Swank noise in traditional imging detectors, can result in increases of relative imprecision to 50% and will impose a severe limitation on the ability of these detectors to determine x-ray spectra and methods will have to be incorporated into new detector designs to overcome these limitations. With the exception of K-escape effects, Se-based and CsI-based detectors could potentially measure spectra with energy RMS imprecision of 3-10%.

International conference on Multimedia Technology

作者： Shufang Zou Murong Jiang Dan Wang Minghua Zhong Yun Pan Yunnan Radio and TV University Kunming China Department of Physics Asahikawa Medical College Asahikawa Hokkaido Japan

Due to the rapidly growth of multimedia communication, video image deblurring has become a hot issue in image processing. As the image size increases, it is difficult to perform the large size image deblurring computation on a single computer in a limited time. One of the most efficient solving methods is parallel computing. In this paper, we first introduce a variational equation for the blurred image, analyze its computing scheme and improve the discretization, then detail the parallel implementation with multithreads programming using OpenMP and MPI on a dual core cluster. Some experimental results show that this method can produce the large size video image deblurring.

It is widely accepted and can be easily verified that any specific voxel in a class of brain single photon emission computed tomography (SPECT) volumes is of a univariate normal distribution. In this research, we conjecture that all the voxels in a class of SPECT volumes are also approximately of a multivariate normal (MVN) distribution from which in terms of the Bayes errors of statistics, an optimal classifier can be designed using quadratic discriminant functions (QDFs). However, the number of training volumes needed for deriving the covariance matrix of an MVN distribution increases quadratically with respect to the number of voxels such that practically the MVN distributions cannot be modeled. To overcome this, we selected a reduced number of voxels and put them into groups based on the P values of two-sided t tests or a greedy algorithm of discrimination between two classes of volumes. We also tried the same approach on the 3D Haar wavelet coefficients which were obtained from the discrete wavelet transform of the voxels. Experiments showed that the accuracies of QDFs, linear discriminant functions (LDFs), and support vector machines (SVMs) were not significantly different in discrimination between Alzheimer's and normal controls verifying that the proposed MVNs effectively model the discrimination information. Moreover, the proposed QDF classifier obtained satisfactory performance.

Retinex-based color correction for displaying High Dynamic Range images

International conference on Signal processing Proceedings (ICSP)

作者： Jinhua Wang Haijiang Bi Institute of Information Technology Beijing Union University Beijing China Datang Software Technologies Co. Ltd

Until now, most of methods for High Dynamic Range (HDR) images focus on tone mapping. They can compress large range luminance values so that they can be displayed on ordinary devices. However, the lighting condition in which the images are taken is not considered. As a result, the mapped images may have color cast. Therefore, to get an image that is similar to direct observation of a scene for human eyes, tone mapping alone for a HDR image is not sufficient. In order to solve the problem, we propose an Orientation-based Retinex (O_Retinex) method serving as color correction for HDR images. On the other hand, local contrast loss may be caused by most tone mapping methods when the dynamic range of a HDR image is quite high. In our paper, a contrast enhancement technique is proposed to solve the problem. Furthermore, the color correction and the tone mapping are processed in parallel for our method, which is the main difference from other methods that serve the tone mapping as a preprocessing. Because the proposed method uses the parallel processing strategy, it can adopt most of tone mapping methods. The only constraint on them is that the ratios among three color channels must be preserved. Experiments show that the proposed method can efficiently reduce color cast induced by lighting condition for HDR images.

International Symposium on parallel and distributed processing with Applications, ISPA

作者： Rabindra Bista Young-Sung Shin Jae-Woo Chang Department of Computer Engineering and Center of Advanced Image and Information Technology Chonbuk National University of Korea Cheongju Chungbuk South Korea

In this paper, we propose a new privacy preserving data aggregation scheme for WSNs. Our scheme applies additive property of complex numbers in order to combine sensor data and preserve data privacy during transmission to the sink node. In addition, for supporting scalability, we propose a novel mechanism in which a special set of real numbers are assigned to sensor nodes as their IDs so that a single bit is sufficient to hold ID of a sensor node during transmission of aggregated data to the sink node. For this, we, first, generate fixed size signatures for the IDs of all sensor nodes and then superimpose the signatures during data aggregation phase. By analytical evaluations, we show that our scheme is more scalable and energy efficient than the existing methods to achieve data privacy and transmit IDs of sensor nodes along with the aggregated data to the sink node.

Embedded multimedia systems are expected to fully embrace the future many-core wave. As a consequence parallel programming is being revamped as the only way to exploit the power of coming chips. While waiting for them we try to extrapolate some lessons learned from current multi-cores to influence future architectures and programming methods. In this paper we investigate the parallelism and scalability of a JPEG image encoder, which is a typical embedded application, on several shared memory machines using the OpenMP programming framework. We identify the Huffman coding as the bottleneck that blocks the application from scaling above a 7x factor. We propose a strategy to parallelize the Huffman coding, which introduces a small degradation in some parts of the image, allowing to reach higher speedup factors. A factor of 18.8x has been reached in SGI Altix 4700 using 22 threads. Contrasting these results with some previous works using message passing architectures we consider that the use of OpenMP on top of shared memory architectures should be reconsidered for future chips in favor of message passing architectures and programming models.

The increasing availability of multi-core and multiprocessor architectures provides new opportunities for improving the performance of many computer simulations. Markov Chain Monte Carlo (MCMC) simulations are widely used for approximate counting problems, Bayesian inference and as a means for estimating very high-dimensional integrals. As such MCMC has had a wide variety of applications in fields including computational biology and physics, financial econometrics, machine learning and image processing. One method for improving the performance of Markov Chain Monte Carlo simulations is to use SMP machines to perform 'speculative moves', reducing the runtime whilst producing statistically identical results to conventional sequential implementations. In this paper we examine the circumstances under which the original speculative moves method performs poorly, and consider how some of the situations can be addressed by refining the implementation. We extend the technique to perform Markov Chains speculatively, expanding the range of algorithms that maybe be accelerated by speculative execution to those with non-uniform move processing times. By simulating program runs we can predict the theoretical reduction in runtime that may be achieved by this technique. We compare how efficiently different architectures perform in using this method, and present experiments that demonstrate a runtime reduction of up to 35-42% where using conventional speculative moves would result in execution as slow, if not slower, than sequential processing.

This paper presents new VLSI architectures for finite impulse response (FIR) filters and discrete wavelet transform, intended for very high-speed signal and image processing. The proposed architectures, based on combining pipeline and parallel arithmetic methods, provide a new and very fast convolution approach with a reduced critical path. The key to this is a clever use of D-latches and multipliers which are efficiently distributed. Furthermore, an advanced discrete wavelet transform (DWT) approach, with an area-efficient architecture, is designed to produce one output in every clock cycle. As a result, a very high-speed is attained. The proposed structure can increase the work frequency (85%) at a low cost of additional hardware elements (55%). The systems are verified, using JPEG2000 coefficients filters, on Xilinx Field Programmable Gate Array (FPGA) devices.

ChinaGrid Annual conference (ChinaGrid)

作者： Jing Zhang Gongqing Wu Haiguang Li Xuegang Hu Xindong Wu School of Computer Science and Information Engineering Hefei University of Technology Hefei China Department of Computer Science University of Vermont Burlington USA

In the field of data mining, clustering is one of the important methods. K-Means is a typical distance-based clustering algorithm; 2-tier clustering should implement scalable clustering by means of dividing, sampling and knowledge integrating. Among those tools of distributed processing, Map-Reduce has been widely embraced by both academia and industry. Hadoop is an open-source parallel and distributed programming framework for the implementation of Map-Reduce computing model. With the analysis of the Map-Reduce paradigm of computing, we find that Hadoop parallel and distributed computing model is appropriate for the implementation of scalable clustering algorithm. This paper takes advantages of K-Means, 2-tier clustering mechanism and Map-Reduce computing model; proposes a new method for parallel and distributed clustering to explore distributed clustering problem based on Map-Reduce. The method aims to apply the clustering algorithm effectively to the distributed environment. The extensive studies demonstrate that the proposed algorithm is scalable, and the time performance is stable. Meanwhile, adding number of cluster nodes would improve the time performance of clustering.
