it is matlab code and is for systems and signals by porakis that is very good for all

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

说明：  对输入的一有理Z变换表达式（输入分子和分母系数序列），分别画出： （1）零极点图 （2）z在单位圆上时z变换所对应的DTFT的幅度谱和相位谱 （3）逆z变换所得序列，在各种不同的收敛域下（包括了右边序列，左边序列和双边序列的情况） (the importation of a rational expression Z-transform (input coefficient of the numerator and the denominator sequence), respectively paint : (1) The pole-zero plan (2) z in the unit circle at z transform the X corresponding to the amplitude spectrum and phase spectrum (3) Inverse z transform sequences derived from the convergence of various jurisdictions (including the right sequence, the sequence of the left and bilateral series))

提供了adaboost Algoritm的工具箱，该算法是一种迭代算法，其核心思想是针对同一个训练集训练不同的分类器(弱分类器)，然后把这些弱分类器集合起来，构成一个更强的最终分类器(强分类器)。 (Adaboost is an iterative algorithm, the core idea is the same training set for training the different classifiers (weak classifier), then these weak classifiers together to form a stronger final classifier (strong classification) .)
