使用快速阈值迭代收敛（FISTA）求解图像去模糊问题，内含多个m文件和一个Amir Beck 写的说明文件-MATLAB code for total variation-based deblurring with FISTA，including a helper document by Amir Beck

纹理识别，LTV，通过求梯度，进而求图像的局部总变差，对指纹图像进行纹理提取(Texture recognition, LTV, by seeking gradient, and then find the local image of the total variation, the fingerprint image texture extraction)

广义全变分的matlab源码，主要用于图像去躁及图像复原，可直接运行，去躁效果不错(Generalized total variation matlab source code, mainly used for image de-restoring and image restoration, can run directly, the de-restoring effect is good.)
