Abstract :
A simple, easy to implement real-time lossless image coding algorithm which takes into account the pixel-to-pixel correlation in an image is presented. The algorithm has built-in limits to the variance in the size of the codewords, and seems to react robustly to mismatch between the assumed and actual statistics. Because of the limited dynamic range in codeword size it is not expected to have significant buffer overflow and underflow problems. Test results using this algorithm are presented
