Two-dimensional Cross-entropy Thresholding Segmentation Method for Gray-level Images
灰度图像的二维交叉熵阈值分割法

Based on the explanation and illustration of the one-dimensional cross-entropy thresholding segmentation method proposed by Li & Lee,a two-dimensional cross-entropy thresholding method was proposed.Considering the disadvantage of high complexity and large computation of two-dimensional method,a fast recursive formula was presented also.Compared with the traditional two-dimensional Otsu's method,the new method can be better adapted to the cases that the variance between the object and the background is large...
