Abstract
Presents a general decorrelating algorithm for signals like edges in a hierarchical subband coding scheme. It consists in first analyzing the highest frequency subbands and in predicting the signal in the other bands. The analyzing step should determine the edge orientation and collect information about the evolution in different bands of the signal perpendicular to the edge orientation. A numerical example shows the efficiency of the orientation analysis
