An Image Positioning Method of Automatic Random Walker Based on IFS Edge Detection

The segmentation method of classical random walker needs to select seed points artificially, and may cause incomplete or inaccurate segmentation. In view of these problems, this paper presents an image positioning method of automatic random walker based on IFS (Intuitionistic Fuzzy Set). IFS edge detection method is used to get the edge information of image, and then the connected domains are found out in image edge using the morphology method. Select the central pixels of each connected domain as seed points for automatic random walker, and then segment the IFS edge image by random walker. Experimental results show that the proposed method overcomes the application limitation of semi-automatic random walker algorithm, and improves the accuracy of image positioning.
