WebDec 5, 2024 · TVL1 provides the highest accuracy optical flow vectors, but is computationally very expensive taking over 300ms per frame. Installing NvidiaHWOpticalFlow 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 … WebHi everyone, I am working on a motion detection algorithm based on optical flow. Specifically, I am using the Dual TV L1 approach (createOptFlow_DualTVL1()). I would like to know if somebody have tried to use this method in realtime (with a "normal" computer). It is getting difficult to find the correct value for every different parameter and to get a solution …
