摘要
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 edgedetection algorithm,Canny algorithm has some good characteristics,such as border closure and so onThis paper not only introduces the Canny algorithm but also makes some improvement to the canny algorithm and brings forward an improved edgedetection algorithm based on dynamic thresholdThe improved algorithm makes up for the disadvantage of canny algorithm,which would lose some edges during detecting nonstandard images with blurred edgesThe algorithm is a practical edgedetection algorithm
