2-dimensional motion-analysis in object-oriented coding

This paper describes a motion analysis algorithm in the object-oriented coding for video sequences and objects in the two consecutive frames of the video sequence are assumed to have moved in translational motion only. It incorporates the knowledge of the border coding process which exploits the temporal redundancies between successive image frames. After segmentation, the boundary information of an object can be obtained by employing a chain-coding technique and then this information is used to estimate the motion in the video sequences. Unlike the conventional scheme, our proposed method calculates individual sets of the mapping parameters for each object requiring motion compensation after segmentation.
