Models Matter, So Does Training: An Empirical Study of CNNs for Optical Flow Estimation

14 Sep 2018Deqing SunXiaodong YangMing-Yu LiuJan Kautz

We investigate two crucial and closely related aspects of CNNs for optical flow estimation: models and training. First, we design a compact but effective CNN model, called PWC-Net, according to simple and well-established principles: pyramidal processing, warping, and cost volume processing... (read more)
