A question that’s cropped up a few times, and while I did a quick test that seemed to work, I wanted to get the official verdict.
If you need a non rectangular tracking image (eg a round badge/pin), how should we prepare the image for training? Obviously the issue is that with a round design, we don’t know what background the camera will be seeing in the “corners” of the tracked area.
I tried using a transparent PNG, and in my very brief tests it seemed to work: the tracking seemed to work OK regardless of what background the badge was sitting on. But I didn’t have time to fully test it.
Am I right - is that the correct approach? Does the training, and the subsequent recognition/tracking allow for parts of the image to be ignored?
