Sensor-Guided Optical Flow [PDF]
2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021 This paper proposes a framework to guide an optical flow network with external cues to achieve superior accuracy either on known or unseen domains. Given the availability of sparse yet accurate optical flow hints from an external source, these are injected to modulate the correlation scores computed by a state-of-the-art optical flow network and guide ...
