自适应滤波，基于工频干扰自适应滤波器，，，，(Adaptive filter, based on power frequency interference adaptive filter,,,,)

说明：  多目标规划的概念是 1961年由美国数学家查尔斯和库柏首先提出的。多目标最优化思想，最早是在1896年由法国经济学家V.帕雷托提出来的。他从政治经济学的角度考虑把本质上是不可比较的许多目标化成单个目标的最优化问题(The concept of multiobjective programming was first proposed by Charles and Cooper, American mathematicians, in 1961. The idea of multi-objective optimization was first put forward by the French economist v. Pareto in 1896. From the perspective of political economy, he turned many objectives that are essentially incomparable into optimization problems of a single objective)

algorithm to calculat the Lyapunov exponent from time series.

RBF方法对一维函数进行插值实例，选用的函数为MQ函数，可与高阶多项式插值对比，说明RBF方法克服了龙格振荡问题。(RBF method for one dimentional function interpolation, where the Runge oscillation is disappear.)

there is some code in matlab that will provide help in the field if digital image processing.it includes the code of extracting region of interst, median filter, nearest neighbour point sampling technique, negative of an image etc. and it is done by myself because i am doing becholar of computer science.it does not include any copyrighted content.i hope it will help thoes people that required help in the field of digital image processing.
