Hi, I found this is a very interesting theoretical paper with good practical justification.
I was wondering whether you could help me resolve the question about the experiment setting of CSMRI:
In Section 6 (Compressed sensing MRI.), the paper said the CSMRI results are evaluated in 30% sample with additive Gaussian noise \sigma=15/255. However, I cannot understand the meaning of noise intensity here, as the value range in Fourier space is indeed no longer 0-1 (or 0-255).
In your implementation, the value range of input image is [0-1], while the intensity of added noise is 15 rather than 15/255 described in the paper (note both 15 and 15/255 have no clear physical meaning in Fourier space)
Thank you very much!
