| Abstract: | A multifractal analysis method to the problem of image edge detection is presented. By computing the local Hoelder exponent of each pixel in the image and its multifractal spectrum, and selecting proper range of the dimension, then the edge information of image is given. Experiment results show that this method is effective for edge detection by selecting proper range of the dimension, giving the eminent and detailed edge of the original image. |
