摘要
针对H.264的特点,提出一种快速块匹配搜索算法.该算法充分利用宏块编码模式间的关联特性和运动矢量的统计特征来降低块匹配搜索复杂度。仿真结果表明,该算法在不改变重建图像质量的条件下,大幅度减少了搜索点数,提高了搜索效率,而且避免了DS算法可能陷入局部最佳点的弊端。
A fast matching search algorithm based on h.264 characteristics is put forward.The algorithm makes full use of the relevant characteristics and the motion vector statistical characteristic between macro block coding modules to reduce the block matching search complexity.The simulation data shows that this algorithm sharply reduces the search points,improves the searching efficiency,and avoids DS algorithm falling into the drawbacks of the local optimal point without changing the reconstructed image quality.
