| Abstract: | Some improvements to the Canny algorithm were brings forward, an improved edge-detection algorithm that transform the local gray distributing after opening some windows on original image and get the statistical data of these windows was presented. The algorithm improves result of Canny algorithm when the gray distributing of a image is not good, which is a practical edge-detection algorithm. With the mathematic analysis and test result, it is demonstrated that this method is an efficient improving approach on edge-detection. |
