WebJun 2, 2024 · The architecture consists of NetC (pyramidal feature extractor) and NetE ( optical flow estimator). NetC generates 6-level feature maps, and NetE predicts flow fields for levels 6 to 2. Level 1 is the most extensive feature map (finer). It also employs a coarse-to-fine strategy along with residually updating the flow vectors. WebDec 5, 2024 · The OpenCV implementation of NVIDIA hardware optical flow leverages the NVIDIA Optical Flow SDK which is a set of APIs and libraries to access the hardware on NVIDIA Turing GPUs. Developers desiring low-level control can use the APIs exposed in the SDK to achieve the highest possible performance. chinese food in acadia calgary
