2014-07-30 09:17:01 -0600 | commented question | How do i get the goodness of fit for the result of fitEllipse? I agree this works very well, but could you explain it? I understand that finding the distance from a point to an arbitrary ellipse is a transcendental problem, which is the reason for your posx and posy calculations (transforming from an arbitrary ellipse to a centered, non-rotated ellipse). Why do you use the negative angle? Where does the -0.25 factor come from? Why use only 32 points? Thanks! |
