读取MODIS的HDF文件和ENVI IDL的程序(MODIS ENVI IDL readhdf.pro)

说明：  Matlab脸部识别程序包括 haar feature adaboosting(Matlab including facial recognition program haar featureadaboosting)

这个算术编码是对大量英文文本进行压缩，只适合英文文本压缩（适当修改可以用于图像压缩）(The arithmetic coding is a lot of English text compression, is only suitable for English text compression (with appropriate modifications can be used for image compression))

说明：  Hu不变矩的的一至七个矩的代码以及论文。matalb版本，可直接用。(Matlab Code of Hu Moment Invariant)

说明：  程序功能是把一副倾斜的文字图像矫正过来，通过边缘检测再进行霍夫变换完成(The program function is to correct a skewed text image.)

基于动态规划的检测前跟踪论文十余篇，对于雷达数据处理与目标跟踪方面工作者有较大帮助。(The 11 papers are all about DP-TBD， it is very useful in track before detected. )

用Matlab来实现PCA，并分别求出图像在第一、二、三主分量上的投影。(Using Matlab to implement PCA, and images were obtained in the first, second and third principal component on the projection.)

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).)

用VC实现Canny算子提取图像边缘，提高图像质量(Using VC realize Canny operator extracts image edge to improving image quality.)
