Abstract: The fragmental ellipse fitting algorithm based on least square was studied.The ellipse-constraint algebraic fitting always provides an elliptical solution,but the bias is inevitably added to result because the algorithm involves all the sample data including some much biased data.Based on this situation,the random theory was introduced.First,an ellipse was fitted by six points which were selected randomly.Then the number of points which match the ellipse was calculated.Repeating the process some... More
