Description: 本文提出并得出快速可变块大小运动估计算法，在此基础上分析比较H264、MPEG4、AVC视频编码算法。文中提供的算法减少运算，以较少的运算量获得较高的图像质量。-This paper proposes and investigates fast variable block-size
motion estimation algorithms based on merge and split
procedures for H.264/MPEG-4 AVC video encoding. The
algorithms take advantage of the correlation of the Motion
Vectors (MVs) of the different block-size modes, to achieve
good computation reduction. Experimental results show that the
number of search points can be reduced to about 4 of that
using full-search motion estimation, with negligible quality
degradation. Platform: |

Description: Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the images are a projection of the 3D scene onto a 2D plane. The motion vectors may relate to the whole image (global motion estimation) or specific parts, such as rectangular blocks, arbitrary shaped patches or even per pixel. The motion vectors may be represented by a translational model or many other models that can approximate the motion of a real video camera, such as rotation and translation in all three dimensions and zoom.-Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence.
