Many research works have been developed for stereo image compression purpose by focusing on the disparity compensation technique. For this reason, a great attention should be paid to the generation of the disparity-compensated residual image. Generally, the residual image is computed through a simple substruction of the disparity-compensated reference image from the target one. In this paper, we investigate two techniques for optimizing the computation of the residual image. The obtained results confirm the benefits of these optimization approaches in the context of stereo image coding.
