A new user interaction method called interactive polygons is presented in this paper. These interaction polygons are designed for use with the Active Volume Model segmentation method [1], which deforms with constraints from both Region Of Interest (ROI) and image gradient information. The two kinds of interaction polygons we apply are "merge polygons" and "split polygons" which identify the foreground and background, respectively. Users are allowed to draw these polygons to correct the original
