求图像峰值信噪比，可以用于图像质量的评估。(Peak signal to noise ratio for images that can be used for image quality assessment.)

模糊聚类分割主函数及demo，直接运行就行，当然要有图片，呵呵(Main functions and fuzzy clustering segmentation demo, run directly on the line, of course, have pictures, Oh)

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)

生成相机标定所用的方格图，用于相机标定使用(Generates the grid chart used to calibrate the camera)

说明：  用matlab编写界面，实现直方图均衡化、平均滤波、梯度滤波、Laplacian滤波、Kirsch滤波、Sobel滤波、Prewitt滤波、高频提升等多种功能(Matlab prepared to use interface, the realization of histogram equalization, the average filter, Gradient filter, Laplacian filter, Kirsch filter, Sobel filter, Prewitt filter, multiple functions, such as high-frequency upgrade)

压缩感知中的梯度投影重构算法，经修改可以运用与单像素相机成像(Gradient projection reconstruction algorithm of compressed sensing, modifications can be used with single pixel camera imaging)

说明：  图像分割代码，c++实现(Image segmentation code, c++ Achieve)

说明：  可以实现背景和目标的分离,效果还是不错的(about matlab programe)

说明：  在光学系统中根据光学系统的孔径函数生成MTF曲线(n the optical system, the MTF curve is generated according to the aperture function of the optical system)

本程序包是关于图形处理和人脸识别的,包括人脸Gabor特征提取，canny算子，水线阈值方法等．大家可以一起参考(The package is on the graphics processing and face recognition, including face Gabor feature extraction, canny operator, waterline threshold methods. Together we can make reference)
