Hi all,

I am working on a project where I need to track non-rigid object (in this case a skater) using OpenCV. The skater will be skating along the ramp and the goal is to track his speed along the trajectory. There is also gap between two ramps where he will jump and I need to track his path during the jump also. We will observing the skater along side view. The skater changes his stance differently along the track. Since, the skater is skating on the ramp in a stadium, there is lot of noise/unwanted objects in the background

What would be a good approach to solve the problem in hand using OpenCV? Any suggestions are welcome.

If you mean "track on the image", then the Kalman Filter, Optical Flow, and/or Camshift approaches can be starting points (e.g. pick one).

If you mean "track using ground coordinates", then you'll also want to determine the homography transformation matrix and perform perspective transforms to map between the image coordinates and ground plane coordinates.

Dig into the portion of the manual linked below along with the code examples and then investigate what others have done.,%20OutputArray%20dst,%20InputArray%20m%29
