Definition of contrast-to-noise ratio?

Answer 1

Contrast-to-noise ratio (CNR) is a measure used to determine image quality. CNR is similar to the metric, signal-to-noise ratio(SNR), but subtracts off a term before taking the ratio. This is important when there is a significant bias in an image, such as from haze.
