This paper presents a triangle based motion compensation algorithm which can remedy the drawbacks of the conventional block matching algorithm. We adopt a fast hexagonal matching algorithm based on the second order luminance signal model. Theoretic analyses and experimental results show that the new algorithm can increase the accuracy of motion estimation, improve the quality of the predicted image, and increase the signal to noise ratio.
