A Threshold Image Segmentation Algorithm Directed by Edge Information
边缘信息引导的阈值图像分割算法

Directed against uneven illumination of image,this paper proposes a threshold image segmentation algorithm based on edge detection.According to this method,the continuity of spatial distribution of the objects,background and the illumination has been considered to determine the threshold by using the information of the edge's gradient.Then,the average of the maximum and minimum value near the edge detected by edge detection algorithm is used as the local threshold for the pixels on the edge.Using surface fi...
