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.
Claims39
A method comprising:
- compressing a first scene of an image sequence using a first plurality of foveation zones, each of the first plurality of foveation zones being weighted based on a probability of a viewer looking at a corresponding portion of the first scene, each of the first plurality of foveation zones having a corresponding resolution to ensure that at least one object therein is viewer-recognizable.
A computer-readable medium having computer-readable instructions to direct a computer to perform an act of:
- compressing a first scene of an image sequence using a first plurality of foveation zones, each of the first plurality of foveation zones being weighted based on a probability of a viewer looking at a corresponding portion of the first scene, each of the first plurality of foveation zones having a corresponding resolution to ensure that at least one object therein is viewer-recognizable.
An apparatus comprising:
- an image compressor to compress a first scene of an image sequence using a first plurality of foveation zones, each of the first plurality of foveation zones being weighted based on a probability of a viewer looking at a corresponding portion of the first scene, each of the first plurality of foveation zones having a corresponding resolution to ensure that at least one object therein is viewer-recognizable.
