python 读取图片总结

一、opencv

import cv2 im = cv2.imread('misc/demo.jpg') print(im.shape) # (H, W, C) BGR

二、imageio

from imageio import imread img = imread('misc/demo.jpg') print(img.shape) # (H, W, C) RGB，颜色反转

三、PIL

from PIL import Image import numpy as np img = Image.open('misc/demo.jpg') img = np.asarray(img) print(img.shape) # (H, W, C) RGB，颜色反转
