Claim 16:
17. The system of claim 11, wherein the method further comprises generating a denoised image comprising a denoised array Ī{tilde over (q)} by repeating a second iterative process until a second termination condition is satisfied, where {tilde over (q)} is a total number of iterations of the second iterative process when the second termination condition is satisfied, repeating the second iterative process comprising:
generating a binary mask M from a qth recovered image comprising a recovered array Īq of size Nh×Nw×C, where a first recovered image comprises the reconstructed image and q is an iteration number; and
generating a (q+1)th recovered image by:
generating a non-filtered sampled image according to an operation defined by:

N=(I−Īq)└M 

where:
I is an image array of size Nh×Nw×C associated with the image,
⊙ is an element-wise product operator, and
S is a sampled array of size Nh×Nw×C associated with the non-filtered sampled image;

generating a filtered sampled image by applying a low pass filter on the non-filtered sampled image;
generating a scaled sampled image by multiplying the filtered sampled image by a scalar smaller than 2; and
obtaining the (q+1)th recovered image by adding the qth recovered image to the scaled sampled image.
