Score level fusion method based on multiple oblique gradient operators for face recognition

The traditional gradient is calculated along y and x axes, and its main object is to obtain vertical and horizontal edges in local image patch. However, there exist a lot of oblique edges in image patch besides vertical and horizontal edges. In order to obtain these oblique edges, we introduce multi...
