LAYER EXTRACTION USING GRAPH CUTS AND FEATURE TRACKING

In this paper we present a new method for layer extraction by tracking a non-rigid body with no fixed motion model, in a video. The method integrates the graph cuts approach with robust point based tracking to achieve good tracking of the whole object over frames of a video. With the help of a little user interaction our method can perform layer extraction over irregular motion and difficult object boundaries. To achieve this we apply the 3D graph cuts on a pair of frames and propagate the labels obtained in the earlier frame to new frame by use of robust tracking method. The user is shown the results of the layer extraction and can provide extra strokes to improve the results.
