| 摘 要： | 文章提出了一种基于图像金字塔分解的快速全局运动估计算法.为了提高计算速度与准确性,采用了3层金字塔进行多分辨率计算.在金字塔第3层图像中,进行宏块预判,去除不可靠宏块,通过块匹配算法粗略地求出摄像机运动参数,并将运动参数映射到金字塔第2层.在金字塔的前2层图像中,将宏块预判与基于块的外点去除算法相结合,去除不可靠宏块,...

| Abstract: | This paper presents a fast global motion estimation algorithm based on image pyramid decomposition.In order to improve the calculation speed and the accuracy,a three-level pyramid is utilized in the multi-resolution calculation.In the third pyramid level,the blocks are prejudged and the unreliable ones are removed.The camera motion parameters are obtained by block-matching and mapped to the second level.In the former two pyramid levels,the unreliable blocks are removed by the algorithm of block prejudgment ... |
