Abstract: | Video-based rendering is a viable alternative to traditional realistic image synthesis techniques. It avoids the burden of timeconsuming modeling and expensive global illumination simulation. In this paper we propose a video-based synthesis and animation system for fixed viewpoint scenes that feature rigid objects. We examplify this by using traffic video sequences. In a first stage, we extract vehicles and their trajectories from the example footage using an intuitive semi-automatic segmentation technique. Subsequently, the resulting vehicle “sprites” are dimensionally reduced using PCA in order to effectively extrapolate trajectories from incomplete sequences. Background, occlusions and shadows cast by vehicles are extracted as well. We show that convincing new footage can be synthesized readily from a single input video. Any number and variety of cars can be inserted, and their trajectories can be edited to simulate such traffic scenarios as lane changes and traffic jams. |
