Abstract :
A quadtree segmented two-dimensional predictive coding technique is presented in this paper for exploiting correlation between adjacent image blocks and uniformity in variable block size image blocks. Visual pattern block truncation coding (VP-BTC) is employed to code the high activity 4×4 image blocks, with a set of sixteen visual patterns used to encode the 4×4 bitmaps. Simulation results showed that the new coding technique achieved substantial bit rate reduction with good subjective quality
