Lycon image loading gives different pixel values than Pillow
jalexhurt opened this issue · comments
When using lycon to load an image, the pixel values differ from loading from PIL and converting to NumPy
Reproduce:
import lycon
import numpy as np
from PIL import Image
path = "/path/to/image.jpg"
img1 = lycon.load(path).astype(np.float32)
img2 = np.asarray(Image.open(path)).astype(np.float32)
np.all(img1 == img2)
This will return False
. In my testing the pixel values differ in ~11% of locations and differ by an average of 1.46
So in 11% of the image, if the PIL pixel value is 144, lycon is either around 145.5 or 142.5.
