Paper Abstract

In this paper, we investigate the performance of a segmentation-based motion compensation algorithm for videoconferencing which uses the motion information obtained from a set of analog position sensors. The position sensors provide high resolution motion information which is used to perform an affine transformation-based motion compensation. The simulation results are presented in the form of displaced frame difference (DFD) variance improvement versus the usual block matching algorithm. The proposed algorithm has the following advantages: (1) a very small amount of motion information needs to be transmitted, (2) the error energy is concentrated mainly in the boundary regions which makes it less noticeable, (3) different regions of the frame can be transmitted with different quality, and (4) a smaller computational load than advanced techniques is required.
