function

skimage.color.colorconv:luv2xyz

source: /dev/scikit-image/src/skimage/color/colorconv.py:1438

Signature

def luv2xyz(luv, illuminant = D65, observer = 2, *, channel_axis = -1)

Summary

CIE-Luv to XYZ color space conversion.

Parameters

luv : array_like of shape (..., C=3, ...)

The image in CIE-Luv format. By default, the final dimension denotes channels.

illuminant : {"A", "B", "C", "D50", "D55", "D65", "D75", "E"}, optional

The name of the illuminant (the function is NOT case sensitive).

observer : {"2", "10", "R"}, optional

The aperture angle of the observer.

channel_axis : int, optional

This parameter indicates which axis of the array corresponds to channels.

Returns

out : ndarray of shape (..., C=3, ...)

The image in XYZ format. Same dimensions as input.

Raises

: ValueError

If luv is not at least 2-D with shape (..., C=3, ...).

: ValueError

If either the illuminant or the observer angle are not supported or unknown.

Notes

XYZ conversion weights use observer=2A. Reference whitepoint for D65 Illuminant, with XYZ tristimulus values of (95.047, 100., 108.883). See function ~.xyz_tristimulus_values for a list of supported illuminants.
