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.
Claims33
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.
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.
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.
