WitrynaLucas-Kanade (LK) optical flow algorithm is widely used for moving object detection and tracking by computing the motion vectors of pixels in image sequences. Due to the high computation complexity, optical flow computation is one of the crucial operations in many computer vision applications. This paper presents a low-cost hardware … Witryna1 sty 2024 · Our second contribution revises the gradient flow across pyramid levels. The typical operations performed at each pyramid level can lead to noisy, or even …
WitrynaImproving Optical Flow on a Pyramid Level Pages 770–786 Abstract References Cited By Index Terms Comments Abstract In this work we review the coarse-to-fine spatial feature pyramid concept, which is used in state-of-the-art optical flow estimation networks to make exploration of the pixel flow search space computationally tractable … Witryna23 maj 2013 · The function is called calcOpticalFlowPyrLK, and you build the associated pyramid (s) via buildOpticalFlowPyramid. Note however that it does specify that it's for sparse feature sets, so I don't know how much of a difference that'll make for you if you need dense optical flow.
