Network Parallel Computing Design And Research On Image Compression

Half a century has past since the first computer "ENIAC" had been made. In this period, computer science and technology make an influence far and wide on modern science and technology. In multimedia field, we must emphasize saving and transferring the multimedia data, include text, voice, image, etc. Compressing the text and graphics can cut down data streams, but must pay out a large number of compress computing. At the same time, the unlimitedly demand for the performance of computers lead to the appearance and great developments of parallel processing technique. Consequently, we can develop the parallel arithmetic technique in image processing or image compression.Parallel processing technique deals with many aspects. It includes hardware technique, parallel software, parallel algorithm, etc. But the current international situation is that the development of parallel algorithm is far more behind parallel architecture. We are making the initial researches in many fields.That is why this paper makes network parallel computing and applications as its researching object in which parallel algorithm and applications in image processing are the stress. Firstly, it summarized the basic conceptions of image compress processing, parallel processing technique and parallel algorithm briefly. Then it emphasized on the network parallel computing environment and LogP Model of parallel computation. At last, this paper described the methods of developing parallel algorithm and applications through the designing, analyzing, optimizing, and implementing of digital image Coding parallel algorithm, include intra-frame coding, inter-frame coding, entropy coding, etc.
