skimage2.color.hsv2rgb#

skimage2.color.hsv2rgb(hsv, *, channel_axis=-1)[source]#

HSV to RGB color space conversion.

Parameters:

hsv(…, C=3, …) array_like: The image in HSV 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 hsv is not at least 2-D with shape (…, C=3, …).

Notes

Conversion between RGB and HSV color spaces results in some loss of precision, due to integer arithmetic and rounding [1].
