image=Image.open('1.jpg') 显示图片 image.show() 保存图片 image.save('1.jpg') 三 两者相互转换 在做转换的时候,最重要的一点是:opencv的图像格式是BGR的,而PIL的图像格式是RGB。 在编程的时候往往这些小细节是很容易被忽略,但却是很重要的地方。 1 opencv to PIL.Image opencvImg=cv2.imread('1.jpg...

Python实现OpenCV格式和PIL.Image格式互转 OpenCV转换成PIL.Image格式：import cv2 from PIL import Image import numpy img = cv2.imread("plane.jpg")cv2.imshow("OpenCV",img)image = Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))image.show()cv2.waitKey()PIL.Image转换成OpenCV格式：import cv2 ...
要从PIL 图像转换为 OpenCV 使用: import cv2 import numpy as np from PIL import Image pil_image=Image.open("demo2.jpg") # open image using PIL # use numpy to convert the pil_image into a numpy array numpy_image=numpy.array(pil_img) # convert to a openCV2 image, notice the COLOR_RG...
