Verbessertes Verfahren zur Teilbandbildkodierung und Einrichtung zur Durchführung dieses Verfahrens

摘要

This technique for coding images involves filtering the original input image into subband images using successive high-pass and low-pass filterings over a tree-shaped filter with each tree filtering stage involving re-scaling operations adjusted to keep the subband image signal dynamics substantially stable throughout the filtering tree. <IMAGE>
