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 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; and accumulating brightness of detected motion attention areas to generate, with respect to time, a motion attention model for the video data sequence.
