Abstract

We propose a simplified motion estimation method which provides motion vectors for all types of motion compensation used in MPEG-2. The method is a result of applying a newly introduced approximation to the canonical three-step method described in the MPEG-2 Test Model. It reduces the number of necessary computations in the second and the third steps to less than 1%, and that of data transfers to about 8% of the canonical method. Total complexity of the proposed method is nearly that of the full-pel search motion estimation
