Recent development of depth sensors has facilitated the progress of 2D-plus-depth methods for 3D video representation, for which frame-rate up-conversion (FRUC) of depth video is a critical step. However, due to the computational cost of state-of-the-art FRUC methods, real time applications of 2D-plus-depth is still limited. In this paper, we present a method of speeding up the FRUC of the depth video by treating it as part of a video coding process, combined with a novel color-mapping algorithm is adopted to improve the quality of temporal upsampling. Experiments show that the proposed systems saves up to 99.5% of the frame interpolation time, while achieving virtually identical reconstructed depth video as state-of-the-art methods.
