Inpainting-based multi-view synthesis algorithms and its GPU accelerated implementation

Holes and cracks filling is the most important issue in depth-image-based rendering algorithms. This paper proposed an inpainting-based depth-image-based rendering algorithm for virtual view synthesis. Firstly, a texture-based interpolation method is applied for cracks filling. Then, the inpainting-based algorithm is used for holes filling. Finally, the graphic processing unit is employed to realize the proposed method. Simulation results show that the proposed algorithm has 51 times speeded up for synthesis virtual view with better quality.
