Abstract
In this thesis, we present an interactive graph cut based video segmenta-ion system. Recently, graph cut based segmentation tools become prevelantor image/video segmentation problem. However, most of the previous workseal with color information only. Such systems could fail under the conditionhat there are regions similar in color between foreground and background.nfortunately, it is usutally hard to avoid. Especially when the objects areilmed under a natural environment. To make it more pratical to use, weropose criterion other than color to conduct the segmentation. Through ourbservation, motion is a natural choice, since it is usually the case that fore-round and background has different motion pattern. Moreover, we also ex-end the Progressive Cut to the temporal-spatial video volume. Experimentshows that by combining color and motion information, our system outper-orms the previous works.
