Conference on parallel and distributed methods for image processing

This work analyzes the computation distribution in applications generated by a multilevel knowledge-based system for image processing called SVEX.(1) This distribution has been carried out on a heterogeneous workstation network, trying to take advantage of the availability and frequent infra-utilization of this computational resource. The parallelization is based on message-passing tool parallel Virtual Machine (PVM).(2) Firstly SVEX and its computational scheme are described, detailing the structure of the first level (the Pixel Processor). Then different distribution paradigms are studied, selecting for its implementation the parallelism based on the data. Considering this alternative, the research addresses two fundamental problems: analysis of basic load-balancing schemes and obtaining-a model for predicting parallelization behavior as new machines are added to the computational network. The results produced in a series of experiments permit the comparison of load-balancing schemes and the validation of the proposed model. The experiments include the processing of both static images and sequences.

The communication overhead in many multiprocessor computing platform is a critical factor over performance. In this paper we will present communication performance of a large processing array built with TI 320C40 DSPs. Inter-processor communication is provided by message passing which is a common method used in multiprocessors systems. The system is developed for image processing therefore transmission of large data blocks and various forms of communication are required frequently. The processor used in this system has six built in communication links. They are X-bit, bi-directional links with a speed of 20 Mbytes/sec. A processing array built with these processors employs MIMD paradigm and static interconnection. In this paper, the communication performance of such DSP network is investigated and performance results are presented. The communication functions include broadcasting, scattering, gathering and point to point transmission of messages.

Two-dimensional (2D) Discrete Fourier Transform (DFT) frequently needs to be performed in the digital image processing. Although the computing time of 2D DFT can be dramatically reduced by using 2D Fast Fourier Transform (FFT), the processing speed of a very large array is yet intolerable. The development of parallel processing system promotes the application of 2D FFT. In this paper, we present the implementation of 2D FFT as a general procedure by row-column method and vector-radix method based on a general-purpose massively parallel processing system-DAWN 1000 developed in China. Even though the 2D FFT has parallel characteristics in nature, the requirement of corner-turning and the existence of data communication make its implementation more complicated. We analyze the impact of the machine capacity and the computing complexity on the algorithm efficiency and evaluate the implementation in terms of the arithmetic operations as well as the data transfer. The comparison of the two methods shows the fact that each method has its own advantages and disadvantages. Combining their traits, we design a new implementation algorithm concerning its flexibility, the efficiency and the complexity of the communication. As an example, we fulfill the spaceborne SAR image processing by using the new approach.

Conference on parallel and distributed methods for image processing

Visual media processing is becoming increasingly important because of the wide variety of image and video based applications. Block rotation is an important operation in different image/video processing tasks such as graphics, fractal processing, pattern matching and image registration. Remote sensing, medical imaging, computer vision, computer graphics, and video coding are typical applications of digital image rotation. However, a hardware implementation of the block rotation algorithm has not been realized and software implementation is slow. Hence, they are not suitable for real-time execution. In this paper, we propose a novel method for block rotation, which is fast and suitable for hardware implementation. The algorithm employs area based interpolation. Experimental results have shown the performance enhancement compared to classical interpolation algorithms at a similar level of complexity.

Conference on parallel and distributed methods for image processing

A heterogeneous system for image processing was designed. The system consists of two layers with an array of DSPs in the low level layer and an array of PCs in the high level layer. The system resembles two stage multi-layers architecture. In the preprocessing phase, image data is delivered to the low level processors and operations are handled by using SPMD paradigm. The processed data is delivered to the high level processors where feature extraction and recognition tasks are performed. Apparently, the performance of this system is highly depended on communication mechanism used. The communication between two heterogeneous processing layers is a critical design issue and will be described in this paper. In our design, we have employed QuickRing. QuickRing provides a high transfer rate, 160Mbytes/s, and supports Multicast mode of data transmission that is suitable for broadcasting of data.

Contract-Linda is a novel programming architecture for heterogeneous parallel machines particularly suited to image processing. Previous research has concentrated on static and pre-determined scheduling of computation and on fine grain parallelism. Pre-determined scheduling is satisfactory in cases where the computational process is fully deterministic. However with many image interpretation schemes the flow of control and the nature of the computational procedures can only be determined at run-time. In this paper we describe a programming paradigm for coarse grain and task level parallelism. Task management is based on the Contract Net protocol and utilises the Linda. Coordination Language to provide run-time scheduling. This paradigm accommodates a closely coupled network of heterogeneous processing modules which differ greatly in computational capability;modules based on neural networks, semantic networks, vector and scalar processors are accommodated. Contract;Linda allo-cvs specialised heterogeneous machines to be exploited using a straightforward generic programming model. It does this by providing an internal task management mechanism which ensures that the heterogeneous processing elements are used by the tasks most suited to them and exploits dynamic parallelism within the problem as it is solved. By separating the task of describing the problem from that of describing how the work is carried out on the machine (and providing a solution for this problem) we allow applications to be quickly developed which can effectively utilise specialised machines without the need for specialised programming. We report an experiment to re-implement a cell image interpretation system using Contract-Linda.

In this paper, we present the implementation of a volume graphics rendering algorithm using shift-restoration operations on parallel algebraic logic (PAL) image processor. The algorithm is a parallel ray casting algorithm. In order to eliminate shading artifacts caused by inaccurate estimation of surface normal vectors, we use gray level volume instead of binary volume, and apply a low pass filter to smooth the volume object surfaces. By transforming the volume to an intermediate coordinate system to which there is a simple mapping from the object coordinate system, we solve the data redistribution problem caused by nonregular data access patterns in volume rendering. It has been proved very effective in reducing the data communication cost of the rendering algorithm on the PAL hardware.

This paper presents a method for minimizing the total elapsed time spent by n tasks running on m differents processors working in parallel. ?he developed algorithm not only minimizes the total elapsed time but also reduces the idle time and waiting time of in-process tasks. This condition is very important in some applications of computer vision in which the time to finish the total process is particularly critical -quality control in industrial inspection, real-time computer vision, guided robots, .... The scheduling algorithm is based on the use of two matrices, obtained from the precedence relationships between tasks, and the data obtained from the two matrixes. The developed scheduling algorithm has been tested in one application of quality control using computer vision. The results obtained have been satisfactory in the application of different image processing algorithms.

Conference on parallel and distributed methods for image processing

In this article, we would like to detect boundaries of objects with the help of a multiagent system made up of reactive agents. The reactivity being very important, the agents' behavior is very simple (perception-action) : they have the capacity, nevertheless, to adapt locally to what they consider their environment, that is to say the image. An agent can move and has its own position in its environment. The basic behavior for an agent consists of following the highest brightness gradient and inscribing its path, if estimating to be on an edge, in all the agents' shared memory. Its path thus corresponds to edges which are found in the image. Please note that, in order to be noise resistant, the path is actually stored in the shared memory only if it is long enough. The notion of shared memory is very important because it allows the interaction among agents and the coordination of their actions. The agents actually use already found edges for finding new ones or complete those already detected. We have tested this system on different grey scale images scenes, but as well on synthetic scenes allowing analysis of thus obtained results. The results are promising and especially fast. Our multiagent system has been tested on a single-processor computer, and it has been note that the number of agents in a simulation neither affects the quality of the result nor CPU time necessary for segmentation of a given scene. We think that this approach is original in its use of agents and may be used to implement parallel image processing by assigning, for instance, an agent to each processor.
