说明：  ICA源程序，主要用于模拟信号的合成与分解。(ICA source, mainly for analog synthesis and decomposition.)

This function takes a quantized analog signal and calculating the signal to noise ratio SNR

遗传算法的源程序,包括选择、交叉、变异等子程序(Genetic algorithm source code, including the selection, crossover and mutation subroutine)

em算法的代码，以及K-means算法代码(em algorithm code, and the K-means algorithm code)

My code is implementation of classic snakes, according to the article of Active contour model. I m making reduction of external curve to the center which searching for extremum (the strongest intensity gradient of edge).

大地坐标变换，转换经度很高，修改正了反变换有0.6误差的错误。下载即可使用。(Geodetic coordinate transformation, the conversion of longitude is very high, change the inverse transform has 0.6 error. You can use to download. )
