Abstract

This paper presents a new full-search block-matching algorithm for a lip reading user authentication system. The proposed algorithm reduces the computational load by eliminating non-candidate blocks from the search window using an approximate DC values. This computational reduction leads to enhanced performance in terms of low power consumption and fast motion vector estimation. A low power VLSI implementation of the algorithm is presented along with experimentation results.
