Fast way to convert rgb to lab in python

Is there a quick way to convert RGB to LAB in Python3 using D50 sRGB?

Python-Colormath too slow

skimage use D65

Solution

  • For now, the white reference in skimage cannot be passed as a parameter (pull request welcome), but here is a workaround:

    from skimage import color
color.colorconv.lab_ref_white = np.array([0.96422, 1.0, 0.82521])
lab = color.rgb2lab(image)
