2. Agenda SNR definition Calculation Method Visual Results Results Conclusions

3. Definition Traditionally, SNR has been defined as the ratio of the average signal value to the standard deviation of the background. However, when presented with a high-contrast scene, many imaging systems clamp the background to uniform black, forcing to zero, artificially making the SNR infinite. In this case a better definition of SNR is the ratio of the average signal value to the standard deviation of the signal.
