That is true, but we didn't have any issues with RGB.

Also, those values seem fine to me. I think i see the issue. Tower Tracker checks if the goal bounding rectangle is wider than it is tall. So when viewing from sharp angles like that is not going to give you a selected contour. Do you have a test image where the goal is straight on? If not, you can just get rid of this segment of code:

Code:
float aspect = (float)rec.width/(float)rec.height;
if(aspect < 1.0)
    iterator.remove();
