图像边缘检测，并有gui界面的设计 有matlab程序生成exe的部分内容(detection of the image edge and establish the gui)

用Matlab实现的数字音频水印嵌入与提取，包括水印提取，水印嵌入，前后对比等功能。(Using Matlab implementation of the digital audio watermark embedding and extraction, including the watermark extraction, the watermark embedding, and other functions before and after contrast.)

说明：  用于计算图像鲁棒性的峰值信噪比和归一化相关系数。峰值信噪比值越大，说明图像处理效果越好，鲁棒性强，越小越不好。归一化相关系数值越大越好。(Images used to calculate the peak signal to noise ratio and robustness of the normalized correlation coefficient. The greater the peak signal to noise ratio, indicating that the better image processing, robust, the smaller the worse. Normalized correlation coefficient the better.)

此源代码,是一个一种基于MATLAB的程序源码，对2PSK过过程进行编程与开发，并绘出仿真波形，给出功率谱分析 可直接使用。 (This source code is a one kind of MATLAB-based program source code, right 2PSK over the process of programming and development, and plot the simulation waveforms are given the power spectrum analysis can be used directly.)

DCDC全桥变换器的闭环simulink模型，电压闭环PI控制(Simulink for full_bridge DCDC.it was controled by PI controler )

非常实用的关于相像系数的程序，与大家分享，希望能在相像系数仿真上面有所帮助(Very practical program resemblance coefficient, helpful to share with you and hope simulation resemblance coefficient above)

1.median_filter (功能:使用中值濾波器去除雜訊) 2.mean_filter (功能:使用平均濾波器去除雜訊) 3.fl_stein (功能:使用誤差擴散法,將影像量化和混色) 4.Central_limit (功能:畫圖並證明中央極限定理) (1.median_filter (function: use median filter to remove noise) 2.mean_filter (function: using the average filter to remove noise) 3.fl_stein (function: using the error diffusion method, the image quantification and blending) 4.

说明：  数字信号处理中DSP中的matlab编程，有关汉明窗函数，汉宁窗以及凯撒窗的编写。(DSP digital signal processing in matlab programming, the Hamming window function, Hanning window, and the preparation of Caesar.)

一个很小的小波分解和重构的程序，很简单，适合出血泽学习(A small wavelet decomposition and reconstruction process is very simple, suitable for bleeding Ze learning)

this is camera interface code for matlab.
