Shape information reduction apparatus and method thereof and its sequential polygonal approximation method |
摘要 |
<p>Shape information reduction apparatus includes a motion compensation prediction unit 16 for predicting shape information of a current frame using shape information of a previous frame and motion information of a current frame. A subtracting unit 11 subtracts shape information motion-compensation-predicted by the motion compensation prediction unit 16 and a current motion region and computes an isolated prediction error region. A threshold operation unit 12 performs a threshold operation and determines whether to transmit or block information. A contour approximation coding unit 13 predicts a contour of a predicted error region and reduction-codes and transmits the shape information. A contour reformatting unit 14 reformats the contour into an isolated prediction error region. A combining unit 15 combines the isolated prediction error region and a scale information on movement compensation for a predicted current frame. <IMAGE></p> |
