四幅有公共部分的图片，利用MATLAB将其精确拼接成一幅图片-Four sites have public part of the picture, use MATLAB to accurately assemble into a picture

此程序用匹配算法，可以对有重叠部分的全息图进行拼接，并用中值滤波提高亮度-Matching algorithm used in this program, you can have overlapping parts of the splicing graph, and use median filter to improve the brightness
