Fast motion estimation method based on structural similarity
基于结构相似度的快速运动估计算法*

Based on the assumption that the human visual system was highly adapted to extract structural information from the viewing field,this paper proposed a fast motion estimation method based on structural similarity(FMEBS).Aiming at the existent defects of rate distortion optimized(RDO) for H.264 inter coding,FMEBS introduced an image measurement called structural similarity(SSIM) to modify the distortion metric and used the fast inter mode decision approach and efficient search patterns.Experiments show that FMEBS reduces average 2.7% bit rate and 91.2% motion estimating time compared with FS and 1.9% bit rate and 35.6% motion estimating time compared with UMHexagonS while maintaining the similar reconstruction image quality.
