Abstract
Video object cutting and pasting is described. In one implementation, pre-segmentation of video frames into regions is performed prior to a 3-D graph cut segmentation. The 3-D graph cut segmentation uses temporal coherence and a global color model to achieve accuracy of video object boundaries. A 2-D local graph cut segmentation can then be used to refine the boundaries. The boundaries can be tracked within a user-selected sequence of windows and refined using a local color model.
