  • Multi-resolution predictive foveation for bandwidth reduction of moving images
    Publication number: 20030194142
    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. 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.
