Generating a Motion Attention Model
First Claim
1. A method for generating a motion attention model of a video data sequence, the method comprising:
- generating a motion saliency map B to precisely indicate motion attention areas for each frame in the video data sequence, the motion saliency map being based on intensity I, spatial coherence Cs, and temporal coherence Ct values from each location of a block MBij in motion fields extracted from the video data sequence; and
accumulating brightness of detected motion attention areas to generate, with respect to time, a motion attention model for the video data sequence.

Abstract
Systems and methods to generate a motion attention model of a video data sequence are described. In one aspect, a motion saliency map B is generated to precisely indicate motion attention areas for each frame in the video data sequence. The motion saliency maps are each based on intensity I, spatial coherence Cs, and temporal coherence Ct values. These values are extracted from each block or pixel in motion fields that are extracted from the video data sequence. Brightness values of detected motion attention areas in each frame are accumulated to generate, with respect to time, the motion attention model.
