基于方向能量的灰度图像边缘检测

传统的边缘检测算法都是基于亮度梯度的,没有考虑到相位信息对边缘检测的作用。本文针对传统算法的不足,利用边缘方向能量模型,提出了基于方向能量的边缘检测算法,并给出了边缘检测的评价函数。对实验结果从主客观方面进行的分析、对比表明,本文边缘检测算法的结果比较理想。

Edge detection based on Oriented Energy

Because traditional edge detection methods mainly based on Brightness Gradient,don't take the importance of phase information into account.This paper in the view of the traditional arithmetic insufficiency,using Oriented Energy model,puts forward an edge detection arithmetic which based on Oriented Energy,and provides the function of edge evaluation.The experimental results show that the edge detection algorithm of this paper gained ideal result.
