双结构元的图像边缘检测算法研究

Double-structure element edge detection algorithm

边缘检测指在一副有一个或多个物体的场景图中寻找其涉及的三维边界如物体边界,阴影边界,表面突变点等等,如何提高边缘检测的精度使得边缘检测算法具有更高的信躁比是图像处理的经典难题,提出了在形态处理中使用双结构元的算法,提供了一种新的算子,能够很好地检测出图像的单像素宽的图像边缘。

Edge detection is a method which can be used to detect objects edges such as borders, shadows and surface singularity in a target image. How to increase the precision and signal noise ratio of edge detection is the major problem. This paper introduces the double-structure element edge detection algorithm base on morphology edge. This algorithm provides a new morphological operator to detect single pixel width edge in an image.
