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
More info: http://scikit-image.org/docs/0.13.x/api/skimage.color.html#skimage.color.rgb2lab
- 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.
