No conversion from RGB to YUV

I fail to find an easy-to-use function in any Python library (preferrably PIL) for conversion from RGB to YUV. Since I have to convert many images, I don't want to implement it myself (would be expensive without LUTs and so on).

When I do the intuitive:

from PIL import Image
img = Image.open('test.jpeg')
img_yuv = img.convert('YUV')

I get an error:

ValueError: conversion from RGB to YUV not supported

Do you know why this is the case? Is there any efficieint implementation of that in python and maybe even PIL?

I am no computer vision expert but I thought this ocnversion is standard in most of the libraries...

Thanks,

Roman

你可以尝试'YCbCr'而不是'YUV'，即

from PIL import Image
img = Image.open('test.jpeg')
img_yuv = img.convert('YCbCr')

你可以试试这个：

import cv2
img_yuv = cv2.cvtColor(img, cv2.COLOR_BGR2YUV)

我知道它可能会迟到，但scikit-image具有函数rgb2yuv

from PIL import Image
from skimage.color import rgb2yuv

img = Image.open('test.jpeg')
img_yuv = rgb2yuv(img)
