Abstract

This paper describes a new approach for the motion estimation problem of digital video based upon the lowest requirement for residual encoding. Most Encoders today use Mean Absolute Difference (MAD) or Mean Square Error (MSE) as the test for the best match. These tests do not give any meaningful measure of how much data may be needed to encode the residuals. Our technique is based on using a new criterion to determine the best match block. The new criteria is based on the minimum number of coefficients to represent the residuals. Experimental results show that, using the new proposed technique we achieve a higher compression ratio for the same quality.
