motion tracking?

Question

Image processing

Tell me, please, what methods are better to use for tracking a simple object, with a quick change in its position and size?

Answer 1

You have formulated the question in a very general way, in this form it will not be possible to answer specifically. What object do you need to track? Marker/face/person/2d-picture?

Answer 2

You can find so-called features on an object - corners, for example, or edges, in general, singular points and calculate their descriptors using methods like SIFT or SURF. Then look for these points in every frame.

Answer 3

Tennis balls and video camera. )
