说明：  QC-LDPC的BP译码算法，MATLAB实现，简单易懂，已成功(Various encoding and decoding methods of LDPC)

说明：  对一副已经给出的图像进行中值滤波处理，利用罗伯特算子、索伯尔算子、canny算子、拉普拉斯算子，分别进行边缘检测。 具体见说明文档。(A given image is processed by median filter. Robert operator, Sobel operator, Canny operator and Laplace operator are used for edge detection. See the instruction document for details.)

本算法将进行人脸识别，首先进行人脸定位检测，然后根据数据库里给的标签进行人脸识别，将人脸的信息显示在人脸旁边。本算法能取得较好的效果。(The algorithm will perform face recognition, first face detection, and then according to the database to the label for face recognition, the face of the information displayed next to the face. The algorithm can achieve better results.)

说明：  遥感图像.img图像与raw格式图像的之间的转换(remote sensing images. Img images with the raw image format conversion between the)

nsst域内基于区域能量和区域方差取最大值的图像融合算法，简单易懂。主程序高频区域能量取大，低频加权平均，读者可自行修改。(nsst maximum value within an image fusion algorithm based on regional energy and regional variance, easy to understand. Main high-frequency energy to take large area, low-weighted average, readers can modify.)
