Abstract: Motion estimation and compensation form a major part in any video coding scheme. The video coding standard adopted for multimedia applications is the MPEG-4 wherein object-based motion estimation comes into play. However. MPEG-4 uses conventional motion estimation technique that can detect only pure translatiomil motion along the image plane and fails to consider any complex motion of the objects that arises due to rotation, zooming, etc. An efficient way of detecting-complex motion is by using the affine motion model. In this paper, we develop a scheme for estimating affine motion of objects suitable for MPEG-4 video coding thereby achieving high quality. Simulation results demonstrate the efficiency of the proposed scheme in comparison to conventional object-bascd motion estimation techniques.
