one person say me that actual snr is,,,

if noiseImage=noisyImage-originalImage then actual snr=mean(originalImage./abs(noiseImage)) so my question is that "Is snr depends on mean and variance of noiseImage"?

*No products are associated with this question.*

Yes. More noise = lower SNR, and less noise = higher SNR.

*variance* of noiseImage affect the SNR? I don't see how: I just see how the *mean* affects the SNR.
