Paper Abstract

In this paper we propose a new method to code the higher bands in a multiresolution decomposition. These coefficients contain the perceptually meaningful edge information in an image which is usually hard to code due to the inherent non-stationary nature of the signal. The multiresolution decomposition itself has the advantage that it is maximally decimated and the edge extraction operator is the same as the higher band filters. Since the bands are directional the edge extraction process shows preference to edges that have specific orientations -- to take advantage of this directional preference we scan the bands in these directions only and code the data as one dimensional streams. The performance of the coder is promising, though several improvements are being made -- specifically to code edge data that is obtained from scanning in the direction tangent to the edge profile rather than the directions dictated by the filtering process.
