Abstract

Mixed-resolution multiview setups offer great savings in both, costs regarding the equipment acquisition and complexity refering to data transmission and storage. However, for applications like free viewpoint television, high-resolution images are desired from all available camera perspectives. Therefore, high-frequency information of adjacent high-resolution cameras can be used to increase the visual quality of a low-resolution camera perspective. However, due to occlusions, some parts of the scene are invisible in the high-resolution views and cannot be synthesized from the reference images. In this paper, a novel high-frequency extrapolation method is proposed, utilizing additional sampling points pre-estimated by a low-resolution block-matching approach. Averaged over all considered test sets, the proposed method achieves a PSNR gain of 0.94 dB with respect to the unrefined signal extrapolation algorithm.
