Adaptive algorithm of edge detection based on mathematical morphology

Abstract

As different structure elements and different scale elements play different roles in removing noise and retaining image details,an adaptive algorithm of edge detection based on multiple structure and multi-scale elements was presented.Firstly,general edge detectors were improved to increase the details of image edge.Secondly,the weights were determined adaptively by calculating the entropies of the edges-detected.Finally,the edges of multiple structure elements detection and the ones of multi-scale elements detection were fused to achieve the final image edges.The experimental results show that the proposed algorithm,compared with a few classic algorithms of edge detection,can effectively eliminate the influence of noise variety on the edge detection,better retain the image details,and adaptively detect the complete and successive edges.
