Web29 de nov. de 2024 · Prerequisites: OpenCV Optical Flow: Optical flow is known as the pattern of apparent motion of objects, i.e, it is the motion of objects between every two consecutive frames of the sequence, which is caused by the movement of the object being captured or the camera capturing it. WebThe optical flow method implements an optional affine or projective regularization as described by Farneback. Without the regularization, pixels with low certainty (especially those near edges) tend to have large errors, but the regularization may negatively impact the ability to model local optical flow in the images.
