Detection of rotating objects using MATLAB

I have a video sequence of a cyclist moving and I need to detect the rotating wheels, Is there any way using MATLAB and image processing rotating region can be detected?

Solution

  • You can try training a cascade object detector to detect bicycle wheels in general. You would need to label wheels in a lot of images, which you can do using the Training Image Labeler app.

    Then, once you've detected a wheel, you try using optical flow to see if it is rotating. Or you can see if it is moving across the field of view, and just assume that it is rotating. :)
