In this work, we study a fractal approach of edge detection. This approach is based on the evaluation of the local fractal dimension (in every pixel of the image) by using Gabor filtering. Gabor Filters use several parameters, as: radial frequency and angular frequency. As we will see the choice of these parameters influence directly on the edge detection. Our contribution is using a mathematical tool said variogram that is going to guide us in the selection of the angular frequency. The method is based on exploitation of local indications that permits to affirm the existence of edge in an image on a direction. Results of edge detection are better since there is extraction in privileged directions of the image.
