说明：  经典的大津otsu算法在matlab中的实现程序，每一步都是经典步骤。(Otsu classical Otsus algorithm in matlab implementation process, each step is the classical steps.)

进行纯净信号和加噪信号的时频域显示，及其包络图显示，并计算加噪信号的信噪比、互相关系数、峭度值，对信号进行离散余弦变换。(The time-frequency domain display of pure signal and noise-added signal and its envelope diagram display are carried out, and the signal-to-noise ratio, correlation coefficient and kurtosis value of noise-added signal are calculated.Making Discrete CoSine transform for signal)

包括最后计算压缩图像的峰值信噪比和压缩效果的源码,用于信号特征提取、信号消噪，计算加权加速度。 ( Including the final calculation of the compressed image peak signal to noise ratio and compression of the source, For feature extraction, signal de-noising, Weighted acceleration. )

1. 理解彩色图像的颜色分层原理和方法 2. 利用颜色分层方法对彩色图像进行分层处理 3. 实现对身份证标准图像的背景分离和皮肤区域提取(1 understand the color image color layering principles and methods (2) the use of color layered approach for hierarchical processing of color images 3 to achieve the standard of identity and separation of the background image to extract the skin region)

说明：  全变分模型主要是依靠梯度下降流岁图像进行平滑处理的模型,希望在图像的内部对图像进行平滑,使得相邻像素的差值较小(The total variation model is mainly based on the gradient descent flow year image smoothing model, hoping to smooth the image inside the image, so that the difference between adjacent pixels is small)

实现巴特沃斯低通滤波器的小程序，大家看看能不能参考一下。(Butterworth low-pass filter program, see if you can refer to.)

MATLAB图像处理 Hough霍夫曼直线检测(MATLAB image processing Hough Hoffman line detection)

说明：  Z源逆变器开路三相SVPWM调制，注入了三次谐波分量。(Open-circuit Three-phase SVPWM Modulation of Z-source Inverter)

二值图像连通域分析，和MATLAB中bwlabel函数功能相似(Connected domain analysis of binary image, and bwlabel similar function in MATLAB)

粒子滤波跟踪，还算不错的一个demo，调试验证可以通过(Particle filter tracking, fairly good one demo, debug and verify through)
