Video Frame Interpolation Via Exceptional Motion-Aware Synthesis

In this paper, we propose a novel video frame interpolation method via exceptional motion-aware synthesis, in which accurate optical flow could be estimated even with exceptional motion patterns. Specifically, we devise two deep learning modules: exceptional motion detection and frame interpolation with refined flow. The motion detection module detects the position and intensity of exceptional motion patterns in current frame given the past frame sequence. The flow refinement module refines the pre-estimated optical flow for synthesizing the intermediate frame using the information of exceptional motion. The proposed modules improve the quality of the synthesized intermediate frame by making the optical flow robust against exceptional case of motion. Experimental results showed that the proposed method outperforms the state-of-the-art methods qualitatively and quantitatively.
