A traditional false-color satellite image of Las Vegas. Grass-covered land (e.g. a golf course) appears in red. In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images.

A pseudo-color image showing activation of the primary visual cortex during a perceptual task using functional magnetic resonance imaging (fMRI) During visual search experiments the posterior parietal cortex has elicited much activation during functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) experiments for ...
The grayscale or color rendering transformation applied to images for display should be stored as a DICOM Presentation State object. These objects support grayscale and true color images, as well as the application of a pseudo-color lookup table to grayscale images. Presentation states can also record any zooming and panning (displayed area ...
In this image, both RGB and Natural Color System color pairs are provided. It may be necessary to zoom to adjust the image. Some people may be able to see the color "red-green" in this image by letting their eyes cross so that both + symbols are on top of each other. In this image, both RGB and Natural Color System color pairs are provided. It ...
Sometimes these monochromatic images are displayed in pseudo-color, where changes in color are used rather than changes in intensity to display changes in the signal. This technique, called density slicing , is useful because although humans have much greater dynamic range in intensity detection than color overall, the ability to see fine ...
Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images. [1] [2] Such illusions have been reported for over a century and have generally been attributed to some form of chromatic ...
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
Pseudo-solarisation (or pseudo-solarization) is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or light areas appear dark.
