Depth image based rendering(DIBR) is an effective method for virtual view synthesis. But synthetic images often contain distortion, the main problem is ghost effect and some holes of varying sizes. To cope with the ghost effect, the color correction of reference views is first used, and then two fusion methods are combined which are depth-based color image fusion and direct color image fusion. Inverse warping is adopted to fill cracks. In order to fill the remaining disocclusions, the image inpainting with depth map is used to get a better virtual view. Because the process of image inpainting is very time-consuming, the inpainting algorithm on GPU is implemented to accelerate the inpainting process based on compute unified device architecture(CUDA). Experimental results show that our proposed method improved the quality of virtual view synthetic images, and the image inpainting algorithm based on CUDA implemented also significantly reduced the time of hole filling.
