convert_colorspace(arr, fromspace, tospace)

Valid color spaces are:

'RGB', 'HSV', 'RGB CIE', 'XYZ', 'YUV', 'YIQ', 'YPbPr', 'YCbCr', 'YDbDr'

Notes

Conversion is performed through the "central" RGB color space, i.e. conversion from XYZ to HSV is implemented as XYZ -> RGB -> HSV instead of directly.

Parameters

arr : (..., 3) array_like

The image to convert. Final dimension denotes channels.

fromspace : str

The color space to convert from. Can be specified in lower case.

tospace : str

The color space to convert to. Can be specified in lower case.

Raises

ValueError

If fromspace is not a valid color space

ValueError

If tospace is not a valid color space

Returns

out : (..., 3) ndarray

The converted image. Same dimensions as input.

Convert an image array to a new color space.

Examples

This example is valid syntax, but we were not able to check execution

>>> from skimage import data
... img = data.astronaut()
... img_hsv = convert_colorspace(img, 'RGB', 'HSV')

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
