Mainly deals with the modification to related matching algorithm based on gray scale and minimum matching algorithm on gray scale, using gradated in-and-out amalgamation algorithm to make the image link together smoothly and seamlessly.

• 针对基于灰度相关的匹配算法进行改进；提出了基于灰度差极小值的匹配算法；采用渐入渐出的融合算法；使图像达到平滑、缝的拼接.
