JPEG 2000 Still Image Compression/Decompression System Software Realization
Ge Xiang · Journal of Changshu Institute of Technology · 2008
The paper presents all the encoding and decoding system of JPEG 2000,the new ISO/ITU-T Standard for still image coding compressing.The author describes the original background,conception and key techniques,analyses the raising algorithm,which will become an optional algorithm of JPEG2000.The author has realized a simple JPEG 2000 encoding/decoding system based on the scaling-based algorithm wavelet with program.And the enquality and capacity of the image are simply compared with the old image,in order to select the vary compression ratio and obtain good image.
