将没有exif文件信息的裸RAW数据转换成YUV422格式的数据.(Exif file information will not be the bare RAW data into YUV422 format.)

Statistical information such as the number of patterns, the mean and standard deviation of each pattern are used to represent the background. Statistical difference (such as 3_principle) is used to judge the target pixel. Complex dynamic background modeling has a large amount of computation. In the Gaussian mixture background model, it is considered that the color information between pixels is uncorrelated and the processing of each pixel is independent of each other. For each pixel in a video image, the change of its value in a sequential image can be seen as a random process that produces pixel values continuously, i.e. Gaussian distribution is used to describe the regularity of color rendering of each pixel in single mode (single peak) and multi-mode (multi-peak).)

根据图像的颜色对图像进行分割，里面有多个方法，一种是RGB色彩分割，一种是K均值聚类，还有对视频处理分割，有多个测试图(According to the color image on the image segmentation, there are multiple ways, one is RGB color segmentation, one is the K-means clustering, and video processing division, a plurality of test pattern)

基于NSCT变换的自适应去噪，里面包含仿真图(image denoising)

混合高斯模型提取视频帧前景背景图像，经试验验证准确率比较高(Mixed gaussian model to extract video frame prospects background image)

屏幕放大镜源码，程序调用API函数，在时钟的周期事件下设置窗口透明样式并复制放大图像，形成放大镜的效果。(Screen magnifier source , the program calls API functions , set the window transparent style event in the cycle of the clock and copies enlarge the image , forming a magnifying glass effect.)

北斗二代接收机中的跟踪程序，模块有载波环（二阶FLL，三阶PLL），FLL辅助PLL,码环是用二阶DLL，再用载波环辅助码环(Compass II receiver tracking program, module carrier ring (second-order FLL, the third-order PLL), FLL auxiliary PLL, code ring is by Second DLL, then the carrier ring auxiliary code ring)

说明：  海森矩阵在图像处理中有许多应用，此代码为海森矩阵的matlab代码(The Hessian matrix has many applications in image processing. This code is the matlab code of the Hessian matrix.)

在IDL中运行，可以将多光谱、高光谱等多波段影像拆分为为单一波段影像(It works in IDL and it can split multibands into single band)
