matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如修改不严重，可提取隐藏信息，如果修改过多，则只能确定是否有修改，而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)

绘制板材的lamb频散曲线，给定材料的横波波速及纵波波速即可绘制其频散曲线(The draw plate of lamb dispersion curve, given the material the shear wave velocity and longitudinal wave velocity can draw their dispersion curves)

A good book on WiMAX networks.

应用SIMULINK搭建适用于风力发电系统的风速模型，包括阵风，自然风等风速类型叠加出符合要求的风速模型，为风力发电系统的仿真提供合理的风速 (Application of SIMULINK to build a wind power generation system is suitable for wind speed model, including gusts, wind speed and other types of natural wind out wind speed superposition model to meet the requirements to provide a reasonable wind speed for the simulation of wind power generation systems)

Tracking of visual phenomena is hard. Very, very hard. And frustrating. You should try not to get discouraged by poor tracking results, but rather concentrate on the specific reasons why your tracker may not be performing well. Is the bad performance predictable from the theoretical properties of the tracker? If so, that s a valuable observation that will serve you well in the future

说明：  图像双边去噪的matlab代码，是当今主流的效果好而且速度快的去噪方法(Image bilateral denoising matlab code, is the mainstream of today s effective and fast de-noising method)

说明：  通信原理 数字基带传输实验 matlab程序(communication theory Digital frequency-hand mode experiment)

trapezoidal sums and example with sin-function

使用RGB模型来进行人脸检测，识别的结果还可以，可以作为其他检测方法的对比(use RGB model for face detection and recognition of the results can also can serve as a contrast detection method)

信号频谱分析的MATLAB实现程序 内附多个源代码，可作学习参考(Analysis of the signal spectrum to achieve the MATLAB program containing a number of source code, reference can be used for learning)
