convert-colorspace

convert_colorspace

skimage.color.convert_colorspace(arr, fromspace, tospace) [source]

Convert an image array to a new color space.

Parameters:	arr : array_like The image to convert. fromspace : str The color space to convert from. Valid color space strings are ['RGB', 'HSV', 'RGB CIE', 'XYZ']. Value may also be specified as lower case. tospace : str The color space to convert to. Valid color space strings are ['RGB', 'HSV', 'RGB CIE', 'XYZ']. Value may also be specified as lower case.
Returns:	newarr : ndarray The converted image.

Notes

Conversion occurs through the “central” RGB color space, i.e. conversion from XYZ to HSV is implemented as XYZ -> RGB -> HSV instead of directly.
