Abstract:

Canny algorithm is one of the commonly used edge detection algorithms. After effective improvement, the Canny algorithm can quickly and efficiently complete the accurate identification of the image edge positions. It plays an important role in computer vision, image analysis and other fields. Based on the concept and implementation steps of edge detection, different improvement methods of Canny algorithm are introduced. The Canny algorithms are classified and summarized according to the different improvement methods, and the edge extraction results before and after the improvement are compared and analyzed. The application and development prospects of the improved Canny algorithm are discussed. The current problems are summerized and the future research direction is proposed.
