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. Each
foveation zone in the scene has a corresponding resolution to ensure that
at least one object therein is viewer-recognizable. 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. Each foveation
zone in the other scene has a corresponding resolution to ensure that at
least one object therein is viewer-recognizable.
