Image edge detection based on omnidirectional multiscale morphology

On the basis of mathematical morphological operation, omnidirectional multi-scale morphological structuring elements are defined in order to suppress noise and adapt to different edge in the image. An approach of image edge detection based on omnidirectional multiscale morphology is constructed by weight adding combination of morphological operation .The results of simulation demonstrate that the method performs better not only in edge detection but also in noise-suppression than classical edge detection operator.
