H.264/AVC uses variable block size motion estimation (VBSME)
to improve coding gain. However, its complexity is significant
and fixed regardless of the required quality or of the
scene characteristics. In this paper, we propose an adaptive
complexity algorithm based on using the Walsh Hadamard
Transform (WHT). VBS automatic partition and skip mode
detection algorithms also are proposed. Experimental results
show that 70% - 5% of the computation of H.264/AVC is required
to achieve the same PSNR.
