| 摘 要： | 针对ARPS算法中初始预测运动矢量不够精确并且ARPS算法针对不同宏块采用相同搜索策略的问题,在深入研究ARPS算法原理的基础上,提出一种基于自适应扁平搜索模板的新的快速运动估计算法.本文在算法的初始预测运动矢量、算法提前终止准则等方面提出了新的观点和方法,同时针对物体的不同运动趋势采用不同的搜索模板.实验证明,本文提出的改进算法在不影响图像编码效率的前提下较大地降低了计算复杂度.

| Abstract: | Due to ARPS algorithm's initial motion vector prediction is not precise enough and ARPS algorithm has the same search strategy for different macroblocks,Through the in-depth study based on the principle of ARPS algorithm,proposed a flat template based on adaptive search of new fast motion estimation algorithm.In this paper,put forward new ideas about the initial prediction motion vector algorithm,early termination criteria and through the trend of the object's different sports using different search templat... |
