基于边缘保持平滑滤波的Canny算子边缘检测

Edge Detection of Canny Operator Based on the Edge Preserving Smooth Filter

在Canny算子实施边缘检测前,运用具有边缘保持性能的滤波器做预处理.仿真实验主、客观分析表明,边缘保持滤波预处理的Canny算子较原有Canny算子在边缘检测性能方面有一定的改善;边缘保持滤波器性能的定量分析和比较,对预处理滤波器和Canny算子边缘检测参数的选择有一定的指导意义.

Implementing the pre-processing with the edge preserving filter before the Canny operator, the subjective and objective analysis of the simulation tests shows that the Canny operator with the edge preserving filter is better than that without the pre-processing filter in the property of the edge detection,and the result of filter＇ eomparison is instructive to the future choice of filter and filtering parameters.
