An object of low-contrast visual texture surrounded by a field of uniform visual texture appears to have higher contrast than when presented on a field of high-contrast texture. This illusion was observed by Charles Chubb and colleagues and published in 1989. [2] An empirical explanation of the Chubb illusion was published by Lotto and Purves ...
Contrast (vision) Six renditions of a rocky shore photo with incremental contrast levels, clockwise from bottom left. Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) visible against a background of different luminance or color.

Histogram equalization accomplishes this by effectively spreading out the highly populated intensity values which are used to degrade image contrast. The method is useful in images with backgrounds and foregrounds that are both bright or both dark. In particular, the method can lead to better views of bone structure in x-ray images, and to ...
Contrast-to-noise ratio (CNR) [1] is a measure used to determine image quality. CNR is similar to the metric signal-to-noise ratio (SNR), but subtracts a term before taking the ratio. This is important when there is a significant bias in an image, such as from haze. [2] As can be seen in the picture at right, the intensity is rather high even ...
Divine Love Conquering Earthly Love (1602–1603), showing dramatic compositional chiaroscuro. In art, chiaroscuro (English: / kiˌɑːrəˈsk (j) ʊəroʊ / kee-AR-ə-SKOOR-oh, -SKURE-, Italian: [ˌkjaroˈskuːro]; lit.
