Video composition by spatiotemporal object segmentation, 3D-structure and tracking
A stereo vision based system for composition of natural and computer generated images is presented. The system focuses on the solution of four essential tasks in computer vision: disparity estimation, object segmentation, modeling and tracking. These tasks are performed in direct interaction with each other using novel and available multiview analysis techniques and standard computer graphics algorithms. The system is assessed by processing natural video sequences. Selected results are reported.
