Abstract
A subband coding system which dynamically adapts to the local orientation of image features is investigated. In particular, the re-orientation scheme proposed by Taubman and Zakhor (1994) is used in conjunction with a separable octave-band subband decomposition. This is then followed by efficient coding techniques such as embedded zero trees, trellis coded quantization, and stack-run coding. The coded images demonstrate the superior subjective performance of the proposed methods
