perform_nlmeans_mex.cpp

A toolbox for the non-local means algorithm

/*=================================================================
% denoise - denoise an image.
%
%   [M1,Wx,Wy] = perform_nlmeans_vectorized(Ma,H,Ha,Vx,Vy,T,max_dist,do_median,mask,exlude_self);
%
%	Ma is the image used to perform denoising.
%	H is a high dimensional representation (generaly patch wise) of the image to denoise.
%	Ha is a h.d. representation for Ma.
%	Vx is the x position of center of the search in Ma (same size as H).
%	Vy is the y position of center of the search in Ma (same size as H).
%	T is the variance of the gaussian used to compute the weights.
%	max_dist restricts the search size around position given by Vx,Vy.
%	mask_process restrict the area of filtering (useful for inpainting)
%	exclude_self avoid to take into account the central pixel
%	
%	M1 is the denoised image
%	Wx is the new center x position for next seach (center of best fit)
%	Wy is the new center y position for next seach (center of best fit)
