Abstract

Popular techniques employed to code the Displaced Frame Difference (DFD) treat it no differently from an ordinary image for coding purposes. Since the DFD is generated by the process of motion compensation, such methods do not fully exploit the underlying redundancies. This paper is aimed at proposing a DFD coding method which exploits such redundancies while incurring negligible information overhead. The key idea is to predict locations of high DFD concentration which occupy small portions of the image and use this predicted information (which is also available to the decoder with out additional information transmission) to improve the quality of the decoded image. Two key features of the proposed approach are its compatibility with any transform based DFD coding scheme and negligible information overhead. Tests with a fully functional video coder show the efficacy of the proposed approach.
