| Abstract: | A new hierarchical relaxation method for edge detection is proposed. It is shown that using multiresolution information of the image hierarchical representation, the weighted coefficient in the iteration process can be selected by taking into account the values at the high level of the pyramids as a measure of the local edge features in the images. Satisfactory detection can then be obtained at all points of the images, and the eonvergence rate of the relaxation is greatly improved. This method is also useful for obtaining the complete border of the objects in the images. |
