WebSep 9, 2024 · Compared to Flownet 1.0, the reason for Flownet 2.0’s higher accuracy is that the network model is much larger by using stacked structure and fusion network. As for stacked structure, it estimates large motion in a coarse-to-fine approach, by warping the second image at each level with the intermediate optical flow, and compute the flow update.
