A product correlation algorithm of image registration based on feature and spatial-temporal correlation was presented.
提出了基于特征和时空关联的积相关图像匹配算法。
The algorithm uses a difference image histogram of four directions to measure the influence of spatial correlation, and temporal correlation is measured by the histogram of frame difference.
该算法利用视频序列中各帧的四方向差分直方图度量隐写对空间相关性的影响，同时利用相邻帧帧间差分的直方图度量隐写对时间相关性的影响。
