椭圆拟合程序的源码，用于图像处理。 Descr iption There are two main methods for least squares ellipse fitting: 1) Minimise algebraic distance, i.e. minimise sum(F(x)^2) subject to some constraint, where F(x) = x'Ax + b'x + c This is a linear least squares problem, an
使用了编程语言：C#，编程工具：Visual Studio 2010实现了对数值计算中Steffensen，Muller（抛物线）非线性方程数值求解；Gauss线性方程组求解；Lagrange，Newton，三次样条插值法数值逼近的winform 软件开发，取代了Matlab方法，便于方法的应用和推广。
Many computer vision problems (e.g., camera calibration, image alignment, structure from motion) are solved through a nonlinear optimization method. It is generally accepted that 2 nd order descent methods are the most robust, fast and reliable appr
James Martens JMARTENS @ CS . TORONTO . EDU Ilya Sutskever ILYA @ CS . UTORONTO . CA University of Toronto, Canada Abstract In this work we resolve the long-outstanding problem of how to effectively train recurrent neu- ral networks (RNNs) on comple
The spectroscopic data recorded by dispersion spectrophotometer are usually degraded by the response function of the instrument. To improve the resolving power, double or triple cascade spectrophotometer and narrow slits have been employed, but the t
