source: /_skimage2/color/colorconv.py:255

Signature

def rgb2hsv(rgb, *, channel_axis = -1)

Summary

RGB to HSV 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 HSV format. Same dimensions as input.

Raises

: ValueError: If rgb 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].

Examples

from skimage import color
from skimage import data
img = data.astronaut()
img_hsv = color.rgb2hsv(img)
