Color space conversion

Converts each pixel in a multi-channel image into another colour space

Documentation

Algorithms

grey2cmap

Converts greyscale values after normalization and scaling from 0 - 255 into a matplotlib colourmap.

cmap:

The colormap to use in conversion

More info: https://matplotlib.org/examples/color/colormaps_reference.html

greyscale

Transforms RGB images into greyscale

luminance preserving:

Use weighted average based on separate luminosity of red-green-blue receptors in human eye. Only works for three channel images

hsv2rgb

Interprets input channels as Hue-Saturation-Value (HSV) and outputs Red-Green-Blue (RGB) channels.

More info: http://scikit-image.org/docs/0.13.x/api/skimage.color.html#skimage.color.hsv2rgb

lab2rgb

Interprets input channels as sRGB and outputs CIE LAB channels.

illuminant:

CIE standard illumination spectrum

observer:

Aperture angle of observer

rgb2hsv

Interprets input channels as Red-Green-Blue (RGB) and outputs Hue-Saturation-Value (HSV) channels.

More info: http://scikit-image.org/docs/0.13.x/api/skimage.color.html#skimage.color.rgb2hsv

rgb2lab

Interprets input channels as sRGB and outputs CIE LAB channels.

illuminant:

CIE standard illumination spectrum

observer:

Aperture angle of observer

rgb2xyz

Interprets input channels as sRGB and outputs CIE XYZ channels.

More info: http://scikit-image.org/docs/0.13.x/api/skimage.color.html#skimage.color.rgb2xyz

xyz2rgb

Interprets input channels as CIE XYZ and outputs sRGB channels.
