Abstract:

The existing virtual view synthesis methods generate the images with many artifacts that are annoying, especially for forward virtual viewpoint, and virtual viewpoint generated by reference views with large baseline, due to occlusions and the limited sampling density. In this paper, we propose a new view synthesis method, robust to the above-mentioned problem, consist of three steps, using stereo contents. Firstly, view plus depth data of each viewpoint is 3D warped to the virtual viewpoint. We determine which neighboring pixels should be connected or kept isolated. Polygons enclosed by the connected pixels, i.e. superpixel, are interpolated. Secondly, we blend those warped images by comparing each pixel's depth value to obtain the virtual view, in which non-occlusion holes have already been interpolated by the process in the first step. Thirdly, the remaining holes are filled by inpainting. Our experimental results and comparisons show that the proposed view synthesis method allows smoother view reconstruction, while holes due to occlusion and 3D warping are filled with less artifacts.
