Abstract :
We review the various tools in JPEG 2000 that allow the users to take advantages of the various properties of the human visual system such as spatial frequency sensitivity and the visual masking effect. We show that the visual tool sets in JPEG 2000 are much richer than what was available in JPEG, where only locally invariant frequency weighting can be exploited.
