Object description and recognition based on implicit polynomial curves are applied well. Then, the symmetry detection of the object can be changed to study implicit polynomial curves.
隐含多项式曲线在物体描述和识别中具有许多优点并得到实际应用，因而物体的对称性检测问题可以转换成对隐含多项式曲线的对称性检测来研究。
In this paper a method is proposed to fit data point with implicit polynomial 2D curves, to make the distance from the data points to the curve within the relatively smaller range.
