Parallel Algorithm Based On The Jpeg2000 Image Compression Research

With the development of multimedia and network technology, we canconveniently transmit and exchange digital media products via networks, and we needmore on quality, size and application about digital picture. We wish that we cancompress and reconstruct the picture in different resolution according to oursapplication. JPEG2000 is the newly standard about still image compress behind theJPEG standard. It adopts DWT(Discrete Wavelet Transform) arithmetic onmulti-resolution analytical theory and that JPEG adopts the DCT(Discrete CosineTransform) arithmetic.Parallel processing technique deals with many aspects. It includes hardwaretechnique, parallel software, parallel algorithm, etc. But the current internationalsituation is that the development of parallel algorithm is far more behind parallelarchitecture. We are making the initial researches in many fields.That is why this paper makes network parallel computing and applications as itsresearching object in which parallel algorithm and applications in image processingare the stress. Firstly, it summarized the basic conceptions of image compressprocessing, parallel processing technique and parallel algorithm briefly. Then itemphasized on the network parallel computing environment and LogP Model ofparallel computation. At last, this paper described the methods of developing parallelalgorithm and applications through the designing, analyzing, optimizing, andimplementing of digital image Coding parallel algorithm on JPEG2000 using MPI.
