Edge detection of cord fabric defects image based on an improved morphological erosion detection methods

An improved erosion detection method is proposed in this paper for edge detection of defect image Pulp plaque which is processed by improved morphological filtering. Furthermore, applying some traditional methods, such as difference marginal check method, Laplace edge check method, Sobel edge check method, morphological dilation detection method and morphology of erosion detection method, to detect the image edge. The experiment results show that improvement shape erosion examination algorithm proposed by this article has the noise elimination influence function, and furthermore, can retain the edge detail information of the goal in enormous degree, which is a effective edge detection method.
