在产生混沌伪随机序列的混沌映射中，Logistic映射(Logistic Map)是一种简单而经典的映射。其中u称为分形参数，随着u逐渐增大，出现倍周期分岔现象。可用于密文域图像加密。(Logistic Map is a simple and classical mapping for generating chaotic pseudo-random sequences. U is called fractal parameter, and with the increase of u, period doubling bifurcation occurs. It can be used for image encryption in ciphertext domain.)

先进行高斯金字塔分层，在拉普拉斯分解，最终将两幅局部有模糊的图像进行融合，最后显示清晰图像。(First Gaussian pyramid stratification, in Laplace decomposition, the final two local fuzzy image fusion, and finally show a clear image.)

说明：  行为识别3D卷积神经网络,ucf或者KTH数据集都可以使用(3DCNN for action recognition)

这是基于mean-shift运动目标跟踪的matlab仿真的程序，含有三个M文件(This is based on the mean-shift moving target tracking matlab simulation program, containing three M documents)

快速非局部均值，用来消除噪声，效果良好，适合于细节较多的图像(Fast nonlocal means is used to eliminate noise and achieve good results, which is suitable for more detailed images.)

应用MSER检测子检测图像局部区域来估计图像尺度信息，非常好用！(Applying MSER to detect the local region in images, then estimate the image scale information, very easy to use!)

说明：  基于MATLAB的条形码识别。带GUI可视化用户操作界面。读取条形码，经过一系列预处理，如灰度化，去噪，直方图增强，中值滤波，二值化，腐蚀，识别等。可识别20多张条形码图片，另外可定制二维码的识别，二维码可自定义生成内容，生成二维码，然后嵌入数字水印进行加密传输，接收方提取水印的二维码，识别。(Bar code recognition based on MATLAB. Visual user interface with GUI. Read bar code, after a series of preprocessing, such as graying, denoising, histogram enhancement, median filtering, binarization, corrosion, recognition and so on. It can identify more than 20 bar code images, and can customize the identification of two-dimensional code. The two-dimensional code can generate the content of the two-dimensional code, generate the two-dimensional code, and then embed the digital watermark for encryption transmission. The receiver can extract the two-dimensional code of the watermark for identification.)

RLE压缩算法,对.bmp格式文件进行操作。使用MFC编制界面，可读入位图，压缩后保存位图并显示。(RLE compression algorithm, bmp format file operation. Use the MFC preparation interface, readable into the bitmap compressed to save a bitmap display.)
