利用快速二维嫡的图像分割方法因其运算量大而影响了它的实际使用, 本文经过参数变换用减法代替原来方法中的对数运算同时将算法代替原来的穷尽搜索获得阂值向量来提高求解速度和分割效率-Using fast two-dimensional entropy method of image segmentation because of its large amount of computation to affect its practical use, this after a parameter transformation to replace the original with the subtraction method of computing the same time, the logarithm of the exhaustive search algorithm to replace the original vector to increase the threshold value obtained speed and efficiency of solving the segmentation
