A frame rate up-conversion (FRUC) method for 3D video (3DV) is presented in this paper. Inspired by the fact that moving foreground objects draw more attention of the viewers, in our method depth guided extended block matching (DGE-BM) is adopted to maintain the completeness of the foreground object. We first obtain the motion vector field (MVF) of the interpolated frame via block-based bi-directional motion estimation (ME). And the blocks of the interpolated frame are classified according to the depth information. Then, the boundary blocks are divided into sub-blocks, whose motion vectors (MVs) are estimated using DGE-BM. Finally, the refined MVF is applied to do motion compensation. Experimental results show that the frame interpolation quality of the proposed method achieves significantly improvement comparing with existing algorithms.
