基于matlab用脉冲响应不变法和双线性变换法实现iir数字滤波器的设计(A design of two ways to realise iir digital filter)

this code is skin color detection algorithm

matlab code for image growing

说明：  基于MATLAB平台的微分进化策略的实现(The realization of differential evolution strategy based on MATLAB)

说明：  用pso对bp神经网络进行优化，对pid控制器进行优化设计(Using PSO to optimize BP neural network and PID controller)

相关函数法该方法先由序列估计出自相关函数R，然后对其进行傅立叶变换，得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。 (Correlation function method that the method is estimated by the sequence from a correlation function R, then its Fourier transform, the power spectrum estimation. When the length of delay and data can be compared to a very early age have a good estimation accuracy.)

说明：  对图像进行处理后常需要计算图像的PSNR值和NC值(calculate the PSNR and NC of pictures)
