该代码为文章“Boundary-Finding-based-Multi-focus-Image-Fusion-master”源代码，利用边缘发现来实现聚焦区域的检测，提高了融合图像质量。(It is a novel boundary finding based multi-focus image fusion algorithm, in which the task of detecting the focused regions is treated as finding the boundaries between the focused and defocused regions from the source images. According to the found boundaries, the source images could be naturally separated into regions with the same focus conditions.)
