自适应Canny边缘检测算法研究

在分析传统Canny算子边缘检测原理的基础上,提出了一种自适应Canny边缘检测方法。文中方法在保持了传统Canny算子原有的信噪比高、定位准确和单边缘响应优点基础上,提高了抑制虚假边缘的能力,并且利用全局阈值分割方法自适应确定动态阈值,提高了边缘检测的自动化程度,在实际应用中取得了良好的效果,通过实验证明了自适应Canny边缘检测方法是一种有效的边缘检测改善方法。

Study on the self-adaptive Canny edge detection algorithm

On the basis of analyzing the conventional Canny algorithm,this paper proposed an adaptive edge-detection method based on the canny operator.This method not only keeps the Canny's good performance in good detection,good localization and only one response to a single edge,but also improves the capability of restraining the fake edge and the automaticity of edge-detection based on the Global thresholding method.Through experiments,it is demonstrated that the adaptive edge-detection method in this paper is very effective.
