Deep Video Frame Rate Up-conversion Network using Feature-based Progressive Residue Refinement a
Résumé
In this paper, we propose a deep learning-based network for video frame rate up-conversion (or video frame interpolation). The proposed optical flow-based pipeline employs deep features extracted to learn residue maps for progressively refining the synthesized intermediate frame. We also propose a procedure for finetuning the optical flow estimation module using frame interpolation datasets, which does not require ground truth optical flows. This procedure is effective to obtain interpolation task-oriented optical flows and can be applied to other methods utilizing a deep optical flow estimation module. Experimental results demonstrate that our proposed network performs favorably against state-of-the-art methods both in terms of qualitative and quantitative measures.
