Signature

def rgb2xyz(rgb, *, channel_axis = -1)

Summary

RGB to XYZ color space conversion.

Parameters

rgb : (..., C=3, ...) array_like: The image in RGB format. By default, the final dimension denotes channels.
channel_axis : int, optional: This parameter indicates which axis of the array corresponds to channels.
versionadded 0.19
channel_axis was added in 0.19.

Returns

out : (..., C=3, ...) ndarray: The image in XYZ format. Same dimensions as input.

Raises

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

Notes

The CIE XYZ color space is derived from the CIE RGB color space. Note however that this function converts from sRGB.

Examples

from skimage import data
img = data.astronaut()
img_xyz = rgb2xyz(img)
