  Abstract

In this paper, we propose a hole filling method based on VST that effectively fills the hole area generated by view extrapolation. The conventional VST method generates an interpolated view using a stereo image. In order to fill the hole region occurred when the virtual view is generating , eight images having a viewpoint, spatial, and temporal similarity to the reference image are searched. However, since the number of images to be searched is large and each image is searched by the full search method, the method has a disadvantage of low speed. In case of applying the VST method to view extrapolation, since the hole area is generated more than when view interpolation is applied, it takes more time. Therefore, we propose a new VST-based hole filling technique that reduces search range and computational complexity while maintaining the performance in view extrapolation. First, the number of reference images is reduced by analyzing the usage statistics of reference images. Second, n-step block search method is applied to block search in reference image. Experimental results show that the proposed method increases the speed by 8.5 times and the PSNR by 0.78dB compared with the VST method.
