Python lsq-ellipse

WebThis Ellipse property is an alias for the Circle’s radius. Whereas hradius, major and minor can use Ellipse’s conventions, the vradius does not exist for a circle. It is always a positive value in order that the Circle, like Polygons, will have an area that can be positive or negative as determined by the sign of the hradius. Examples WebThe algorithm takes two different points belonging to the ellipse. It assumes that it is the main axis. A loop on all the other points determines how much an ellipse passes to them. A good match corresponds to high accumulator values. A full description of the algorithm can be found in reference [1]. References¶ Xie, Yonghong, and Qiang Ji.
