一种基于Canny算子的多重边缘检测算法
Multiple Edge Detection Algorithm Based on a Canny Operator
摘要
Abstract
Canny operator was used as a basic operator to have the first time edge detection of the image. After the top-hat transformation of the original image, the second time edge detection was applied. On the base of the top-hat transformation image, logarithm transformation was carried out to start the third edge detection. After stacking up the three results of edge detections and skeletonizing it, a clear and simple image of edge detection was finally got. The experiment showed that the algorithm can well realize the extraction of the edges, especially the weak edges.关键词
