The image edge detection is an important part of image processing. The task of finding the edgesin an image that correspond to true physical boundaries remains a hot topic of image processing.However, classical edge detection algorithms always have localization, because of its relativelyfixed template. And they are only applied to the limited ideal situation. With the development ofmachine learning and data mining, Support Vector Machine (SVM) has gradually been used to theimage edge detection. However, the...
