WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebDec 5, 2024 · Computation of optical flow vectors is a computationally expensive task. However, OpenCV 4.1.1 introduces the ability to use hardware acceleration on NVIDIA Turing GPUs to dramatically accelerate optical flow calculation. NVIDIA Turing GPUs include dedicated hardware for computing optical flow (OF). This dedicated hardware uses …

WebDemonstration of image registration using optical flow. By definition, the optical flow is the vector field (u, v) verifying image1 (x+u, y+v) = image0 (x, y), where (image0, image1) is a couple of consecutive 2D frames from a sequence. This vector field can then be used for registration by image warping. To display registration results, an RGB ...
