Dense optical flow detection using OpenCV's Gunnar Farneback’s algorithm. An example is included: taking a video showing a crowd in movement, the people movement can be described with a set of vectors.
OpenCV demonstrations of selected algorithms related to motion tracking: (1) mean shift, (2) CAMSHIFT, (3) iterative Lucas-Kanade algorithm with pyramids, and (4) Farnebäck's algorithm
Optical Flow Transfer
Examining Farneback and lucas-Kanade optical flows also testing MOG, MOG2, and GMG background subtraction approaches
Optical flow with OpenCV, NvidiaHWOpticalFlow, Machine Learning methods etc.
