Object-by shape information compression apparatus and method and coding method between motion picture compensation frames |
摘要 |
An object-by shape information compression apparatus and a method thereof, which includes a motion compensation prediction circuit provided for motion-compensation-predicting a shape information of a current fame using a shape information of a previous frame and a motion information of a current frame; a subtraction circuit provided for computing a prediction error region by subtracting a shape information predicted by the motion compensation prediction circuit and a current motion region; a threshold operation circuit provided for determining a transfer and disconnection of an information in accordance with time by threshold-operating an isolated prediction error region obtained by the subtraction circuit; a contour prediction circuit provided for compression-coding a shape information by predicting a contour in a prediction error region obtained by the threshold operation circuit; a contour reconstruction circuit provided for reconstructing an isolated prediction error region from a contour coded by the contour prediction circuit; and an addition circuit provided for adding an isolated prediction error region obtained by the contour reconstruction circuit and a shape information of a motion-compensated and -predicted current frame.
