| Abstract(in English) | Depth image obtained by deph camera that can get color and depth information simultaneously is lower resolution than color image. In this paper, we propose depth upsampling method using estimated scene boundaries. In particular, we leverage a spatio-temporal coherency between the color and depth image sequences. We compute motion vectors from color image sequence and we predict current depth image. Using the predicted depth, we estimate scene boundaries. The predicted scene boundaries allow us to reconstruct high resolution depth image. Our experiments show the effectiveness of our method. |
