Abstract:

An edge detection algorithm using improved morphologic operators with multiscale and multistructuring elements is presented in this paper. The competence of antinoise can be improved by the improved morphologic operator when using it to detect image edges. And the use of the idea of multiscale and multistructuring elements can detect more information of edge direction while having better competence of antinoise. The results of experiments show that the algorithm has better competence of antinoise and retains more edge details while detecting more information of edge direction, thus has better applicability.
