K-SVD算法应用，图像去噪，提高图像质量-The K-SVD is a new algorithm for training dictionaries for linear representation of signals. Given a set of signals, the K-SVD tries to extract the best dictionary that can sparsely represent those signals.

Dabov K, Foi A, Katkovnik V提出的BM3D算法的工具箱，是目前实现图像去噪效果最好的方法之一-Dabov K, Foi A, BM3D algorithm toolbox Katkovnik V presented, is currently one of the best methods of image denoising
