skimage2.color.xyz2rgb#

skimage2.color.xyz2rgb(xyz, *, channel_axis=-1)[source]#

XYZ to RGB color space conversion.

Parameters:

xyz(…, C=3, …) array_like: The image in XYZ format. By default, the final dimension denotes channels.
channel_axisint, optional: This parameter indicates which axis of the array corresponds to channels.

Added in version 0.19: channel_axis was added in 0.19.

Returns:

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

Raises:

ValueError: If xyz 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 to sRGB.
