浙江大学的关于提取图像背景的报告（matlab），里面的方法给我很多启示，希望也能给你们一些启示，由于本人是初学者，有些方法还是看不懂！(Zhejiang University, on the extraction of image background report (matlab), inside the method for giving me a lot of inspiration, hope and also give you some inspiration, because I am a beginner, and some way to watch or do not understand!)

说明：  离散傅里叶变换，开发环境是MATLAB。(Discrete Fourier Transform, the development environment is MATLAB.)

matlab部分实用的案例，适合初学者浏览(the case of some practical matlab for beginners visit)

常用的MATLAB变成源代码，对初学者的快速入门很有帮助。(Commonly used MATLAB into the source code for the Quick Start very helpful for beginners.)

说明：  MATLAB，从入门到精通，经典教材。PDF，高清版，有很多实例。(MATLAB, entry to the proficient, classic textbook.)

岭回归函数，基于SVD分解的岭回归函数，已经证明了是非的有用和强大( center input and output, so we can estimate w0 separately since we don t want to shrink w0 )

粒子群优化最优路径算法，和模拟退火算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优(Similar to simulated annealing (SA), particle swarm optimization (PSO) optimizes the optimal path by iteratively searching for the optimal solution from a random solution. It also evaluates the quality of the solution by fitness, but it is simpler than the genetic algorithm rules. It does not have the crossover and Mutation operations of genetic algorithm. It finds the global optimum by following the best values currently searched.)

说明：  用于二叉树寻索，找出在一个确定的矩形中，数量最大的圆或者矩形(treegraf used to find the most round or rectangle in a big rectangle)
