| Abstract: | The defaults in the edge detector available for human face recognition are analyzed and the improved edge detector is proposed: the fast algorithm for the Gauss Differentiation operator increases the computation speed by more than ten times; the OR AND method improves the quality of the binary image greatly and proves to be a good method for the binarization of complicated images. |
