Abstract :
The availability of multi-view images of a scene makes new and exciting applications possible, including Free-Viewpoint TV (FTV). FTV allows us to change viewpoint freely in a 3D world, where the virtual viewpoint images are synthesized by Image-Based Rendering (IBR). In this paper, we introduce a FTV depth estimation method for forward virtual viewpoints. Moreover, we introduce a view generation method by using a zoom camera in our camera setup to improve virtual viewpoint-ts´ image quality. Simulation results confirm reduced error during depth estimation using our proposed method in comparison with conventional stereo matching scheme. We have demonstrated the improvement in image resolution of virtually moved forward camera using a zoom camera setup.
