In this paper, we present some results on the use of N- queen sub-sampling lattices for motion estimation in H.264. For MPEG-4, N-queen has been shown to give better results compared to other existing pixel decimation lattices in terms of spatial homogeneity and directional coverage. We aim to develop a generalized algorithm to select an M- length pattern from an N times N block such that the selected...
This paper presents an FPGA based hardware design for full search block matching (FSBM) based motion estimation (ME) in video compression. The significantly higher resolution of HDTV based applications is achieved by using FSBM based ME. The proposed architecture uses a modification of the sum-of-absolute-differences (SAD) computation in FSBM such that the total number of additions/subtraction operations...
