To solve the problem of ellipse - object - shape parameters detection in noise image, a new detection algorithm using nonlinear data fitting model and cross-reference iterativemethod is proposed.
And then an new iterativemethod is presented to solve the nonlinear equations system obtained from moving least-square approximation.
之后，借鉴牛顿法、平衡法和摄动法对由移动最小二乘法得到的非线性代数方程组提出了新的求解方法。
