Hi there!
I've been wondering of a way to cut down the steps of sorting the transform and thresholding which constructs an image based on specific # of coefficicents. f is the image and M=4096:
R = fft2(f);
s = sort(abs(R(:)));
s = s(end:-1:1);
T = s(M+1);
R = R.*(abs(R)>T);
f1 = real(ifft2(R));
Just a thought. What do you suggest?
