Video frame interpolation aims to synthesize one or multiple frames between
two consecutive frames in a video. It has a wide range of applications
including slow-motion video generation, frame-rate up-scaling and developing
video codecs. Some older works tackled this problem by assuming per-pixel
linear motion between video frames. However, objects often follow a non-linear
motion pattern in the real domain and some recent methods attempt to model
per-pixel motion by non-linear models (e.g., quadratic). A quadratic model can
also be …
