InvFlow: Involution and multi-scale interaction for unsupervised learning of optical flow

Xuezhi Xiang, Rokia Abdein, Ning Lv, Abdulmotaleb El-Saddik

Abstract: Highlights•We utilize the involution operation in our unsupervised optical flow model to improve pixel-wise matching and, accordingly, the estimated flow.•We propose a multi-scale-interaction module to prevent detail loss at each pyramid scale.•We propose a motion-feature-optimization block to improve the motion features.
