Abstract
Directly encoding the image pixel values using noiseless coding techniques such as Lempel- Ziv-Welch codes or arithmetic codes is inefficient as it fails to capitalize on the normally abundant correlation among neighboring pixels. A simple modification that exploits the pixels correlation as in the Delta Pulse Code Modulation scheme can improve the compression efficiency. Motivated by the `adaptive coding by block classification' idea of Chen and Smith, we take into account the pixels non-stationary nature and present a more sophisticated lossless adaptive differential image coding system that can further improve the compression efficiency.
