Abstract. This paper proposes an approach for mathematical morphol-
ogy operators whose structuring element can locally adapt its orientation
across the pixels of the image. The orientation at each pixel is extracted
by means of a diffusion process of the average squared gradient field.
The resulting vector field, the average squared gradient vector flow, ex-
tends the orientation information from the edges of the objects to the
homogeneous areas of the image. The provided orientation field is then
