Abstract

H.264 achieves considerable higher coding efficiency compared with previous video coding standards, whereas the complexity is increased significantly. This paper proposed a novel fast algorithm based on structural similarity (SSIM) in motion estimation (ME) process (FMEBSS), which can greatly reduced the complexity of ME by eliminating the unnecessary search positions and reducing complex prediction modes. Simulation results demonstrate that the proposed method can averagely reduce the coding time by about 50%, and compression ratio is improved at the same time, while the degradation in video quality is negligible.
