Xishun Zhang, Dongquan Zhang, Taotao Li, Shubo Yu · 2018
This paper uses the optimization theory of heuristic search algorithm to realize the extraction of sub-pixel edges. This method can connect the isolated pixel points of the image edge when extracting the image edge, which can obtain more accurate and continuous segmentation image. Compared with image segmentation in the traditional mode, this method breaks through the redundancy of edge points, which not only preserves the edge characteristics of the image, but also improves the segmentation accuracy of the image in the case of 8 neighborhood irreducibility. By comparing the experiment with the traditional method, the method has higher image segmentation precision and wider applicability.
