一种基于Canny算法的边缘提取改善方法

An Improved Edge-Detection Method Based On Canny Algorithm

Canny算法作为一种优化的边缘检测算法,在用于检测图象的边缘时有着边缘上连续性等许多优良特性。在介绍Canny算法的基础上,通过对Canny算法进行改进,提出了一种基于动态阈值理论的边缘提取算法。该算法弥补了Canny算法在对非标准图象的模糊边缘进行检测时丢失边缘的不足,是一种具有实用价值的边缘检测算法。

Being an optimal edgedetection algorithm,Canny algorithm has some good characteristics,such as border closure and so onThis paper not only introduces the Canny algorithm but also makes some improvement to the canny algorithm and brings forward an improved edgedetection algorithm based on dynamic thresholdThe improved algorithm makes up for the disadvantage of canny algorithm,which would lose some edges during detecting nonstandard images with blurred edgesThe algorithm is a practical edgedetection algorithm
