参考来源 - 一种基于非线性灰度变换的弱边缘检测方法The weak edge problem is solved by the classification of different object regions,which uses more global features,rather than simple growth or shrinkage of regions,which is only based on local features.
强调区域的相互作用,可以将弱边界的问题转化到不同物体的分类上,实际效果是对全局性质的特征处理,避免单独区域的扩张或收缩,也避免对弱边界特征的判据只是借助局部性质。
