中文说明：复化三点Gauss-lengend公式求pi，包括主成分分析、因子分析、贝叶斯分析，快速扩展随机生成树算法，独立成分分析算法降低原始数据噪声，多姿态，多角度，有不同光照,最终的权值矩阵就是滤波器的系数。
English Description：
Complex three Gauss-lengend formula to calculate pi including principal component analysis, factor analysis, Bayesian analysis, the rapid expansion of the random spanning tree algorithm, independent component analysis algorithm reduce original data noise and multi pose and multi angle, a different light, the final weight matrix is the filter coefficients.
