Abstract:In this paper we proposed an improved watershed algorithm for the quasi-circle overlapping images of the bars end face. According to the classical watershed algorithm, which often causes over-segmentation, the improved algorithm does a series of pretreatment with the original image, such as sobel filter. With the gradient operator and mathematical morphology method, we firstly obtain the smooth image of the forced local maximum marks. Then, on the basis of the quasi-circle characteristic of the target image, w… Show more
“…Only now can the watershed segmentation function be applied based on the Distance Transform Approach. This approach is regularly used along the watershed function [47][48]. It calculates simply the distance from any pixel to its nearest nonzero valued pixel.…”

“…Watershed transform is considered as a segmentation approach based on regions [17,18]. There are two major classes of watershed transforms, one was proposed by Vincent & Soille, and the other by Meyer [19].…”
