GrabCut is a classical efficient algorithm used in image segmentation. In this paper we provide an approach of video segmentation—an algorithm which is called “GrabCut in local window algorithm” based on GrabCut algorithm. First, make cutout with GrabCut in series of overlap local windows and get corresponding local contour boundaries. Then the contour boundaries in local windows are linked to get...
This paper addresses the problem of natural image segmentation. We develop the interactive image segmentation system and construct two-scale graphs, including region-based graph and pixel-level graph. Building region-level graph is to partition the image into several constituent components. Graph cut is used to extract the foreground object from the image. New data cost functions are defined in the...
