What is optical flow problem?

The main problem with optical flow methods is that the smoothness of their motion does not allow discontinuities of motion across object boundaries in the scene.

What is optic flow example?

Essentially, optic flow is the apparent visual motion that you experience as you move through the world. Suppose you sitting in a car or a train, and are looking out the window. You see trees, the ground, buildings, etc., appear to move backwards. This motion is optic flow.

What is optical flow?

Optical flow is a technique used to describe image motion. It is usually applied to a series of images that have a small time step between them, for example, video frames. Optical flow calculates a velocity for points within the images, and provides an estimation of where points could be in the next image sequence.

What is optical flow equation?

I_xu + I_yv + I_t = 0, where the partial derivatives of I are denoted by subscripts, and u and v are the x and y components of the optical flow vector. This last equation is called the optical flow constraint equation since it expresses a constraint on the components u and v of the optical flow.
