Another method to calculate SNR is by taking the linear ratio between the recorded signal and the total root mean squared noise as shown in the formula below, in which case it is called linear SNR. Signal-to-Noise Ratio in embedded cameras SNR in cameras indicates the signa...
Very interesting approach - I of course tried it immediately and came away with a different result. I have two stacks of Lum subs, one with an FWHM of 2.9px (the "FWHM" stack) and one with an FWHM of 3.8px (the "SNR" stack). When I used your Pixelmath formula (SNR * Mask) +...
so system security is improved.To aiming at the problem of existing watermarking algorithms to ascertain the appropriate strength by repeating experiment or experiential data,the proposed algorithm calculates adaptively watermarking strength by SNR formula based on audio content.Experimental results prove the...

Generally the formula is SNR=20log10(std(signal)/std(noise)) , in your case you have :
The authors in [7] adopted several formulae (Euclidean distance, Pearson correlation, SNR, etc.) for measuring the similarity between the expression levels of a gene g and an ideal gene g ideal in a 2-class problem, where an ideal gene pattern was defined by g ideal = (gideal,1, ...
(ICS-5000, PA-20 column; ThermoFisher Dionex) using a 1 μl injection volume and 45 mM KOH eluent. Sugar peaks were identified in comparison with known sugars, and data were analyzed using the formula previously described with L/G ratio of 1/100 for kernel and cob [61]. T6P and ...
The sample mean and variance dependence can be described by an analytical formula =-=[3, 6, 7]-=-. The noise properties of signal-dependence with a determined relationship between the mean and variance were modeled into a PWLS (penalized weighted least square) cost function, and the cost ...
