Motion-only video compression

Video compression standards are all based on a hybrid coding approach, where the video frames are represented partially as motion information and partially as (residual) intensity information. In this paper we present a new approach to video coding, where the video sequences are represented through motion information only. The new coding approach builds upon the traditional block-based motion compensation scheme, with the residual information coded as motion rather than intensity. Simulations show that the new approach allows video sequences to be coded more efficiently than with the standard hybrid approach. Moreover, the new coding scheme results in significantly clearer images than the standard coding approach
