Abstract: This paper presents an interactive element extraction method for texture image, which is able to simultaneously cut out the repeated texture elements with much less user interaction. Firstly, texture image can be segmented into individual and connected subpatches by using Mean Shift algorithm, and their connectivity can be constructed by using Delaunay triangulation. Secondly, by considering color information and texture feature, a robust measurement distance is redefined, which can precisely capture all repeated texture elements with similar appearance. Finally, this paper further modifies the optimization graphcut model in order to achieve the best texture extraction. The proposed method gets a great better extraction result for the texture image that has foreground and background with similar color, and improves the speed of image segmentation significantly.
