Abstract

An extension of 2D Seam Carving [Avidan and Shamir, 2007] is presented, which allows for automatic resizing the duration of video from stationary cameras without interfering with the velocities of the objects in the scenes. We are not interested in cutting out entire frames, but instead in removing spatial information across different frames. Thus we identify a set of pixels across different video frames to be either removed or duplicated in a seamless manner by analyzing 3D space-time sheets in the videos. Results are presented on several challenging video sequences.
