gauss.rar - this .m file is about the gauss-newton iteration lm_examp.rar - The Levenberg-Marquardt curve-fitting method is actually a combination of two minimization
methods: the gradient descent method and the Gauss-Newton method. gas_newton.rar - Gauss_Newton迭代法,适合于基于优化理论最小二乘法求优化系数,用VC编写 Levenberg-Marquardt.zip - L-M算法的简单介绍及部分matlab程序 newton_iteration.rar - 这是我自己写的亲测可用的matlab 牛顿迭代法函数程序 Depixelizing-Pixel-Art-master.zip - 像素图的去像素化(Depixeling Pixel Art)
从像素图导出一张光滑、与分辨率无关的矢量图,可以任意放大而不会失真
