Abstract: Conventional coding system using translation only motion estimation and compensation system cannot efficiently handle complex inter-frame motion activity including scaling, rotation and various forms of distortion. In this paper, we propose a local affine motion prediction method, which manages to enhance the inter-frame image prediction quality using the conventional motion vectors. Our method is characterized with the fact that no extra bit has to be sent to the decoder for proper decoding. Experimental results show that our method manages to achieve a maximum average bit rate reduction of 1.7% compared to the conventional inter-frame prediction method using translation only motion compensation techniques, at no cost on quality degradation.
