Re: Ellipse Detection

Extracting the luminance is far cheaper than fully converting to HSL. Go ahead and time it. It will be slightly more expensive than extracting one of the planes, and after all, which plane do you use to get black and white?

The 3 is indeed very small, but it is a radius of three, not the diameter and this is about the number needed for full field. If you are up closer, you can set the number higher to avoid small objects from being IDed as the target.
