I'm working on tracking a doughnut shaped target with SIFT as the detector. I just drew this target with a marker and then cut it out with scissors. It works okay but I keep wondering if there's a better pattern I could come up with?
And I know it's a bit dark, but I took this picture with my device's camera. I did try equalizing the histograms of both the target and the incoming image, but it only made a little difference.
Thanks!
