采用GdI+编程实现了，图像的读入，图像像素数据的采集和分析，通过线性判别函数和一个圆形判别函数来分离图像和背景-By GdI+ programming, and read the image, the image pixel data collection and analysis, linear discriminant function and a circular discriminant function to separate the image and the background

PCA(主成分分析法)、LDA(线性判别法)两种方法是主要的线性降维法，有很好的效果，希望对大家能够有用！-PCA (Principal Component Analysis), LDA (Linear Discriminant method) two methods are the main linear dimensionality reduction method, have very good results, in the hope that everyone can be usefu
