FFT

One of Biometrics fields is face recognition & face expression recognition ... 1- In face recognition .. we need to design authentication program by training a neural network ,there are two source codes..one of them is based on Discrete Wavelet Transform with Perceptron Neural Network.. and the other based on Discrete Cosine Transform with Perceptron Neural Network ... 2- In face expression recognition .. we defined the condition of the person (nature,happiness,disgust or anger) this source code is based on Principle component analysis(PCA) .. * we need to now about digital image processing ,neural network and PCA...

说明：  这个源代码实在matlab平台上绘制一个语音序列的语谱图，简单易懂，希望对大家有用！(This source code is a matlab platform voice rendering of the language spectrum sequence, easy-to-understand, useful for all of us hope!)
