MATLAB Code for High-Precision Ellipse Detection and Center Localization
This forked from an existing project. Ellipse features are commonly encountered in machine vision, and high-precision detection of ellipse centers is often required. If you are interested in how to precisely draw ellipses, refer to my earlier share: High-quality Ellipse Detection.
Illustration: This is the source code for the paper. Important: Please use the citation of our IEEE TIP version instead of the arXiv version. The main contribution of the proposed ellipse detector is to both accurately and efficiently detect ellipses in images, which is universally considered as a tough and long-standing problem in the ellipse detection field.

Matlab_Ellipse_Fitting_and_R2_Goodness_of_Fit_Calculation
椭圆拟合
使用Matlab的函数,如fitEllipse或lsqcurvefit,可以对一组散点进行椭圆拟合。拟合的基本思路是最小化每个点到椭圆的距离,得到椭圆的最佳参数(中心位置、长短轴长度和旋转角度)。
拟合优度计算
拟合优度R²衡量的是拟合模型对数据的解释程度。R²值越接近1,表示拟合效果越好。R²的计算公式为:
R² = 1 - (Σ(y_actual - y_predicted)² / Σ(y_actual - y_mean)²)
其中,y_actual为实际数据,y_predicted为拟合值,y_mean为数据的均值。
Matlab
在Matlab中,使用regress或lsqcurvefit来实现椭圆拟合,计算拟合优度时可利用R²公式,或者通过Matlab自带的函数直接获取R²值。
