Abstract

This paper descries a technique for representing motion information in a video coder. We present a novel way of representing motion, based on a dictionary of motion models, as well as related estimation techniques. Motion fields are represented by low-order polynomial-based models and a discrete label field. We develop an adaptive context-based entropy coding technique for the label field. In the paper, we address issues relating to rate-distortion optimal coding. Simulations based on a software implementation of the technique are compared to similar results for classical block- based motion compensation and coding techniques.
