用来读写高光谱遥感影像的matlab代码，支持BSQ,BIL,BIP格式，三种文件格式对应的是头文件*.lxw中的第5个数字，头文件可用写字板编辑(The matlab code used to read and write in Hyperspectral Imagery support BSQ, BIL, BIP, format, corresponding to three types of file formats is a header file*. Lxw in the first five digits, the first file available WordPad editor)

yuv420 to_yuv420p 程序(yuv420 to_yuv420p )

压缩感知的第一本书籍，很不错的，各位大牛每人负责一章，可惜的是还不完全，还有几章未编出，希望对你有用(The first book of compressed sensing, very good, you cow each responsible for a chapter, it is a pity that is not fully chapters compile the hope that useful to you)

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

DPCM 图像的线性预测编码 有完整的运行界面使用简单(DPCM image of linear predictive coding to run a complete easy to use interface)

用于通过三维激光点云数据生成二维的地理参考特征图像，此处以高程作为特征(Used by 3 d laser point cloud data to generate two-dimensional geographical characteristics of reference image, the elevation as features)

Sobel算子就是一种基于方向导数掩模求卷积的方法。通过边缘检测算子可以检测到每个像素的领域并对灰度变化率进行量化，也包括方向的确定。该代码是基于sobel算法的检测程序。(Sobel operator is a directional derivative mask and convolution methods. To each pixel and gray level in the field rate of change can be detected through the edge detection operator to quantify, including direction. The code is based on sobel algorithm testing procedures.)

说明：  图像的重心区域检测 matlab程序实现 可以检测重心区域并设置成希望颜色，对单景物背景图像效果极佳(regional focus image detection Matlab program can detect regional focus and set hope that the color of single features excellent background images)

说明：  基于偏斜度的视频水印源程序, 一个高信息量的水印程序,对大信息量水印有很好的参考价值(Skewness-based video watermarking source, a high amount of information watermark procedures, the large amount of information watermark have a good reference value)
