Real-time virtual view synthesis based on GPU parallel programming

To generate a virtual view image in real-time, this paper propose a fast depth image based rendering method. Firstly, a simple and efficient hole filling method is performed to prevent hole filling error and improve virtual view quality. Secondly, high speed GPU is used to speed up computation speed of DIBR algorithm. Simulation results show that the proposed approach can generate virtual view images 10 times faster than a CPU-based processing. The proposed method not only takes small bandwidth but also achieves good view quality subjectively. It can be applied to real time 3DTV system.
