有限元轴对称问题，平面应变问题，matlab程序(Finite element axisymmetric plane strain problem, matlab program)

说明：  contrast streching matlab code

在matlab环境下，实现了图像的背景图，以及做其他相关运算(In the matlab environment, realize the image background chart, and other related operations)

说明：  视频水印，在每一帧视频帧上嵌入水印，不可见性良好(video waterMarking,embed the watermark on each frame of video,invisibility is mediocre)

说明：  数字语音信号处理中重叠相加法的matlab文件，用于编写帧合并的函数。(In digital speech signal processing, the matlab file of overlapping addition method is used to write the function of frame merging.)

说明：  频域的模态参数识别方法之一，可以对振动信号进行分析处理，得出结构的固有频率，阻尼比，振型系数，方法很好，程序完整(Frequency-domain modal parameter identification methods that can analyze the vibration signal processing, draw the structure of natural frequencies, damping ratio, mode shape coefficient, methods good integrity of the process)

skin detection by back projection and using a .jpg file consist of skin model and detect skin from image that have an similar texture compare to model

该程序模拟了雷达照射区域存在多个点目标，利用线性自回归的方法进行目标估计，包括burg,Yule-Walker法AR 谱估计和修正的协方差谱估计。(The program simulates the radar of the irradiated region there are multiple points of the target, using linear target is estimated from the regression method, including burg, Yule-Walker method AR spectral estimation and the modified covariance spectral estimation.)

this source code is very well
