FlowNet: Learning Optical Flow with Convolutional Networks
Proposes FlowNet, convolutional networks that learn optical flow end-to-end as supervised learning, trained on the synthetic Flying Chairs dataset.
CNNs had excelled at recognition but not at optical flow estimation. This paper builds CNNs that solve optical flow as a supervised learning task, proposing and comparing two architectures: a generic one and another with a correlation layer that matches feature vectors across image locations. Because existing ground-truth datasets are too small to train a CNN, the authors generate a large synthetic Flying Chairs dataset. Networks trained on this unrealistic data generalize well to Sintel and KITTI, achieving competitive accuracy at 5 to 10 frames per second.
