https://charigyang.github.io/motiongroup/ Figure 1. Segmenting camouflaged animals. Motion plays a critical role in augmenting the capability of our visual system for perceptual grouping in complex scenes -for example, in these sequences (MoCA dataset [41]), the visual appearance (RGB images) is clearly uninformative. We propose a self-supervised approach to segment objects using only motion, i.e. optical flow. From top to bottom rows, we show the video frames, optical flow between consecutive frames, and the segmentation produced by our approach.
