Abstract :
We have developed a combinational image representation using the wedgelet minimization algorithm to include orthogonal basis transforms for encoding textural regions and wedgelet for regions with regular boundaries. We show that the representation approach can be used for automatic object contour detection. The preliminary results show that the method is encouraging.
