An Improved Fractional Differential Edge Detection Algorithm

In order to extract detailed edge information, a multi-scale fractional differential edge detection algorithm is proposed in this paper. Firstly, the G-L factional differential is applied to enhance image with two different fraction differential orders (one is small and the other is big), then, the edges can be gotten by subtraction the two enhanced images. Experiments and results showed that the proposed method can not only efficiently detect the edges information of simple objects, but also can detect the edges of complex objects.
