WebJan 16, 2024 · 1 Answer Sorted by: 1 You can use Farneback to estimate dense flow. In OpenCV, the function call is calcOpticalFlowFarneback (). Please note that the initial flow is important and you can use one of OPTFLOW_FARNEBACK_GAUSSIAN or OPTFLOW_USE_INITIAL_FLOW. Web光流特征： 光流（optical flow）是空间运动物体在观察成像平面上的像素运动的瞬时速度。光流法是利用图像序列中像素在时间域上的变化以及相邻帧之间的相关性来找到上一帧跟当前帧之间存在的对应关系，从而计算出相邻帧之间物体的运动信息的一种方法。

WebJul 15, 2015 · The Farnebäck algorithm also employs an iterative approach, with a starting estimate for motion being derived from coarse features and then refined using progressively finer features. The algorithm is described in detail by ( Farnebäck, 2003 ). WebOct 12, 2024 · Optical Flow can be defined as a pattern of motion of pixels between two consecutive frames. The motion can be caused either by the movement of a scene or by the movement of the camera. The main idea behind Optical Flow is to estimate the object’s displacement vector caused by its motion or camera movements method components.
WebOPTFLOW_FARNEBACK_GAUSSIAN uses the Gaussian \(\texttt{winsize}\times\texttt{winsize}\) filter instead of a box filter of the same size for optical flow estimation; usually, this option gives z more accurate flow than with a box filter, at the cost of lower speed; normally, winsize for a Gaussian window should be set to a …
