利用DEV C++ 平台，应FFT实现分段卷积的功能！！！，希望对大家有用-Using DEV C++ platform, should be the function of FFT convolution to achieve sub! ! ! , And I hope useful! ! !

基于分段非线性权重值的Pso算法，实现了图像的加水印，去噪，加噪声等功能，最小二乘回归分析算法。- Based on piecewise nonlinear weight value Pso algorithm, Realize image watermarking, de-noising, plus noise and other functions, Least-squares regression analysis algorithm.
