By changing the form of the threshold value in diffusion function,it can get rid of the noises from image while preserving edges better,and overcome the contradictions between keeping edge and eliminating noises.
通过改进扩散系数函数中的边缘阈值,使其能在消除高梯度图像噪声的同时更好地保持边缘,在一定程序上克服了边缘保持与噪声消除之间的矛盾。
This paper presents a new algorithm for searching the connective regions in the binary image based on the matching between the up contour and down contour points.
基于上下边缘点匹配的连通域搜索算法利用连通域的上下边缘点是一一对应的这一基本原理 ,设计出新的高效二值图像连通域搜索方法 。
