Abstract
A scene of an image sequence is compressed using a number of foveation zones, each foveation zone being weighted based on a probability of a viewer looking at a corresponding portion of the first scene. Another scene of the image sequence is compressed using a different number of foveation zones, each foveation zone being weighted based on a probability of a viewer looking at a corresponding portion of the second scene.
