Medical Image Compression Based on Quadtree Wavelet Fractal
Chong Zhang · Yingxiang jishu · 2005
This paper presented a new algorithm of medical image compression based on quadtree wavelet fractal. In order to improve coding efficiency, we take advantage of the self-similarities within subimages and the similarities cross scales, and we resolved the problem of the long computation time required in the encoding. The test has proved that this algorithm can achieve better compression without diagnostic loss. Therefore, this algorithm can be potentially used in telemedicine and PACS.
