摘要
为解决Canny算子进行图像边缘检测中双阈值的求取需要人工设定的问题,提出了自适应双阈值算法,这样可以针对不同图像实现双阈值的自适应提取,再通过控制技术明确边缘像素,使应用Canny算子检测图像边缘成为现实。经仿真实验表明本算法是有效的。
To solve the problem which the double thresholds should be given by artificially when Canny algorithm was adopted to detect an image edge,in this paper an auto-adaptive double-threshold Canny op- erator has been developed.With the operator the doub- le- threshold can be calculated automatically for any different images,then,some control algorithms should be used to determine the pixels on the edge,so that Canny algorithm for edge detection can be applied in some fields.The results of the simulation experiments show that the algorithm is effective.
