Patent ID: 7116716

Claim:
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 C s , and temporal coherence C t values from each location of a block MB ij in motion fields extracted from the video data sequence; accumulating brightness of detected motion attention areas to generate, with respect to time, a motion attention model for the video data sequence; and wherein I is a normalized magnitude of a motion vector that is calculated according to: I ⁡ ( i , j ) = dx i , j 2 + dy i , j 2 / Max ⁢ ⁢ Mag , wherein (dx i,j , dy i,j ) denotes two components of the motion vector in motion field, and MaxMag is the maximum magnitude of motion vectors.
