WebJul 4, 2024 · The flownet2-pytorch implementation has been designed to work with a GPU. Unfortunately, it means if you don’t have access to one it will not be possible to follow this blog completely. In order to mitigate this problem, sample data generated by the model is provided and allows the reader to follow through with the rest of the blog. WebLiteFlowNet is a lightweight, fast, and accurate opitcal flow CNN. We develop several specialized modules including (1) pyramidal features, (2) cascaded flow inference (cost volume + sub-pixel refinement), (3) feature warping (f-warp) layer, and (4) flow regularization by feature-driven local convolution (f-lconv) layer.
