基于数学形态学的边缘提取方法

论述了图像数学形态学基本方法及扁平结构元素在图像灰度均衡和噪声去除方面的原理,阐述基于图像细节的结构元素选取规则及对图像处理结果的影响,介绍了在医学图像处理中综合应用改进Sobel算子和图像数学形态学方法进行目标边缘的提取过程,提出一种根据图像区域灰度方差自动选取Sobel强度值的算法,并给出一种实用的实现方法和实例。

Method of Picking up Edge on the Basis of the Mathematics Morphologic Subject

This article introduce the theory of using the basic mathematics morphologic methods and the flat structuring element to average the image's grey degree and wipe off the yawp and show the using rule of structuring element based on the image's detail as well as the effect. This article also emphasizes the process of integrating the method of using improved Sobel operator and mathematics morphological to pick up the image target' edge in the medical image processing. At the same time, I put forward a algorithm for choosing the Sobel's magnitude on the basis of the image region's gray variance and give a useful way for these and a example.
