详细说明: function [PSNR, y_est] = BM3D(y, z, sigma, profile, print_to_screen,N2,N2_wiener,Ns,Ns_wiener,tau_match) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % BM3D is an algorithm for attenuation of additive white Gaussian noise from % grayscale images. This algorithm reproduces the results from the article: % % [1] K. Dabov, A. Foi, V. Katkovnik, and K. Egiazarian, "Image Denoising % by Sparse 3D Transform-Domain Collaborative Filtering," % IEEE Transactions on Image Process ing, vol. 16, no. 8, August, 2007. % preprint at http://www.cs.tut.fi/~foi/GCF-BM3D. % % % FUNCTION INTERFACE: % % [PSNR, y_est] = BM3D(y, z, sigma, profile, print_to_screen) % % ! The function can work without any of the input arguments, % in which case, the internal default ones are used ! % % BASIC USAGE EXAMPLES: % % Case 1) Using the default parameters (i.e., image name, sigma, etc.) % % [PSNR, y_est] = BM3D; % % Case 2) Using an external noisy image: ...展开收缩
