Abstract
A coding system and method for a bit-plane is disclosed. A bit-plane is decomposed or segmented into at least a background area and a foreground area. A number of encoders are provided for efficiently encoding the background area and the foreground area respectively. Accordingly, the performance of compression is substantially improved by this data or texture segmentation.
