ok it seams reasonable that its caused by canny because with other edge detection method (starburst) the ellipse fit works fine. Certainly 0.4 px isn't too bad. But my aim is a very high accuracy and the outliers are clearly systematic errors so they should be avoidable.

Do you suspect that there is something wrong with our implementation of Canny? Or can it be improved? If so, it would be well worth investigating further! Stéfan
