FlowNet2

lastmod 2026-11-10created 2019-11-294 edits

FlowNet 2.0 is the successor to FlowNet, which estimates optical flow between two frames directly with a CNN. It stacks several networks, warping the image with the flow from the previous stage and then correcting the residual, and combines a separate network for small displacements, greatly improving accuracy. The original Caffe implementation and NVIDIA's PyTorch implementation are publicly available.
