A Lossless Medical Image Compression Scheme Using Modified S-Tree Structure
Chi‐Shiang Chan, Chin‐Chen Chang · 2005
The medical images have an important characteristic that the pixel-to-pixel correlation is very close. In order to preserve this characteristic, we propose a lossless medical image compression method in this paper. Our method builds the modified S-tree structure to make each block contain similar pixels. Therefore, our method can reduce the needed number of bits to record those pixels. The experimental results also show that our method is better than other methods in almost all cases.
