说明：  一篇英文文献，文中介绍的方法是先把图像分块，用熵值作为衡量每块图像的信息多少；计算每个图像块的熵值，熵值越大，信息含量就多。但是仅仅把熵值大的图像块拼在一起得到的融合图像有明显的不连续性，文中介绍了消除这种不连续性的方法
(An English literature, the paper introduces the method is to first image block, using entropy as a measure of how much each piece of image information calculate the entropy of each image block, the greater the entropy, information content, the more. But only the entropy block large images side by side with the fused image obtained obvious discontinuity, the paper introduces the method to eliminate this discontinuity)
