Paper Abstract

Motion estimation in hybrid image sequence coders is commonly done with block matching. In this paper we present another approach using detailed motion estimates for compensation. Such motion estimates have given good results when applied for frame interpolation[1]. In our case they enable us to reduce the prediction error significantly at the cost of a more complex motion estimate. We thus code this motion estimate with loss coming to a tradeoff between the accuracy of the estimate and the amount of bits necessary to send it as side information to the receiver. Our simulation results show that the same performance range as with a block matching based coder is reached.
