Abstract :
In this paper, we have introduced a new approach to deal with motion estimation block distortion measure (BDM) which has a great role in performance comparison of various methods. The proposed method generates lower BDM, by employing transformed matrices of original frames to compute motion vectors regardless of the algorithm employed as motion estimator. Our experimental results that use the semi DPCM predictor residual matrices as the transformation tool, justify the proposed approach
