In this work, we propose to explicitly detect the occlusion<br>by exploiting the depth information for video frame<br>interpolation. The proposed algorithm is based on a simple<br>observation that closer objects should be preferably synthesized<br>in the intermediate frame. Specifically, we first estimate<br>the bi-directional optical flow and depth maps from<br>the two input frames. To warp the input frames, we adopt a<br>arXiv:1904.00830v1 [cs.CV] 1 Apr 2019<br>flow projection layer [2] to generate intermediate flows. As<br>multiple flow vectors may encounter at the same position,<br>we calculate the contribution of each flow vector based on<br>the depth value for aggregation. In contrast to a simple average<br>of flows, the proposed depth-aware flow projection<br>layer generates flows with clearer motion boundaries due to<br>the effect of depth.
