翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Contrast-to-noise ratio ： ウィキペディア英語版 Contrast-to-noise ratio Contrast-to-noise ratio (CNR)〔http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0077089〕 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. As can be seen in the picture at right, the intensity is rather high even though the features of the image are washed out by the haze. Thus this image may have a high SNR metric, but will have a low CNR metric. One way to define contrast-to-noise ratio is: :$C\; =\; \backslash frac$ where ''S''''A'' and ''S''''B'' are signal intensities for signal producing structures ''A'' and ''B'' in the region of interest and ''σ''o is the standard deviation of the pure image noise. ==See also== *Contrast resolution 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Contrast-to-noise ratio」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
