Evaluation of view synthesis algorithms for mobile 3DTV

Abstract

View synthesis algorithms suitable for mobile devices are presented and discussed. The focus is on low complexity rendering methods that enable line wise processing. A full pixel accurate rendering algorithm is compared to two algorithms using sub pixel accuracy: One sub pixel accurate method applies a linear interpolation, while the other method utilizes rendering in an up-sampled domain. An analysis of the rendered views and the corresponding stereo views is given. In the evaluation especially aspects on 3D impression, hole filling in disoccluded areas and flickering were investigated. Finally, optimized versions of the evaluated algorithms are presented and their computational complexities are discussed.
