Shape-Recognation

matlab的绘图程序，希望对大家有用。(matlab drawing process, in the hope that useful to everyone.)

图像隐藏和数字水印。采用在空域隐藏，在每个象素的bit位的低位藏入图片。采用在DCT系数上附加信息的方法进行。(image hiding and digital watermarking. Hidden in the airspace used in each pixel of the low bit-into the possession of photographs. Using the DCT coefficient Additional information on the methods.)

This is Room Impulse Response.Everybody can download it to discuss.

基于监督学习的一种非线性数据降维方法，可以很好地将低维特征从其所在的高维流形中提取出来，用于数据分类。(A nonlinear data dimension reduction based on supervised learning method, is a good way to the lower dimensional feature extracted from its place of higher dimensional manifold, used for data classification.)

alpha-beta滤波器是一种很实用的滤波器，可以和卡尔曼滤波，信息滤波器做比较，对于初学者有很大帮助(alpha-beta filter is a very practical filter can Kalman filter, the information filter comparison, are very helpful for beginners)

matlab基于灰色理论的去除粗大误差的代码(remove coarse error matlab code based on gray theory)

说明：  本实验的目的是了解非参数估计--parzen窗估计，对数据进行Parzen窗估计和设计分类器。并分析窗口宽度h对分类的影响。(The purpose of this study is to understand the non-parametric estimation- parzen window estimation, Parzen window estimate of the data and design of classifiers. Window width h and analyzed the impact on the classification.)

说明：  关于超宽带的一系列仿真包括高斯波形各阶导函数波形频谱以及采用高斯导函数的跳时超宽带仿真程序(On a series of ultra-wideband waveform simulation including the Gaussian wave function of the first derivative spectrum and the use of Gaussian derivative function of time-hopping ultra-wideband simulation program)

说明：  1/3倍频程分析。有需要做这方面研究的同志们可以好好看一下。(1/3 octave analysis. There is a need to do research in this area can be a good look comrades.)
