MATLAB CODE FOR EDGE PRESERVING

stbc编码qpsk调制的误码率,需要的可以下载了学习一下(stbc编码qpsk调制的误码率)

该程序主要进行重力一位界面的反演，该程序精度准确,具有很好的实际应用效果。(The program mainly for gravity inversion of an interface, the program precision, with good practical results.)

基于Logistic混沌映射的图像加密 将图像数据转换成二进制数据，并采用Logistic进行混沌序列生成，然后设定阈值将其转换成二值序列，之后，设定加密规则，将二进制图像数据与混沌二值序列进行加密运算，实现图像加密(Based on Logistic chaos mapping image encryption)

二次规划的matlab程序，非常实用，注释很详细，希望对大家有帮助！(Quadratic programming matlab program, very practical, very detailed comments, we want to help!)

霍夫曼信源编码，针对一串数据 进行霍夫曼压缩 得到霍夫曼树(Huffman coding)

MFCC参数和LPCC参数需要频繁使用的语音的说话人识别分析还需要使用大量的这些特征参数,这就需要研究MFCC和LPCC算法和参数提取的原则。因为我们需要了解与人交谈的过程中,我们要进行建模 率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(MFCC parameters and LPCC parameters are parameters of speaker recognition which requires frequent use of voice analysis also need to use a lot of these characteristic parameters, This requires research MFCC and LPCC algorithm and the principle of parameter extraction. Because we need to understand the process of talking to people, we want to conduct a speaker modeling the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula)

神经网络matlabtollbox,对编成很重要(Neural network matlabtollbox, very important for the formation)

因子分析法matlab源代码，能将为数众多的原始指标变量经过分析综合为少数几个公共因子变量,从而大大减少计算的复杂度。(Factor analysis matlab source code, can go through a large number of original indicator variables comprehensive analysis to a few common factor variables, thus greatly reducing the computational complexity.)
