Abstract
There are still many problems, especially the coordination between edge detection accuracy and anti-noise performance, although the traditional image edge detection method has been greatly developed. In this paper we propose a key technique based on image edge detection algorithm which adopts the Canny operator to accomplish the job of edge detection and foreground object extraction from the perspective of image processing, also has been compared with other detection methods. The experimental results show that this algorithm is able to raise the sensitivity of foreground object extraction evidently in comparison with some traditional image edge detection methods.
