1.PIL转ndarray from PIL import Image import numpy as np import cv2 img=Image.open(path) #PIL转ndarray img=np.array(img) img=img[:,:,(2,1,0))] #show cv2.imshow('img',img) cv2.waitKey(0) #write cv2.imwrite(path,img) 2.ndarray转PIL #ndarray转PIL img=Image.fromarray(cv2.cvtColor...
# 1、PIL.Image转换成OpenCV格式: import cv2 from PIL import Image import numpy path = 'F:/File_Python/Resources/face_images/LZT01.jpg' img = Image.open(path).convert("RGB")#.convert("RGB")可不要,默认打开就是RGB 没有找到站点() #转opencv #img = cv2.cvtColor(numpy.asarray(image),cv2...

PILimg=Image.open('PILimg.jpg')img=np.asarray(PILimg)OpenCVimg=img[:,:,::-1]cv2.imwrite(' OpenCVimg.jpg',OpenCVimg) 当然也可以参考这篇文章Python OpenCV格式和PIL.Image格式 互转中的方法. 所以不是必要情况还是建议只选择其中一个使用。
PIL和cv2是python中两个常用的图像处理库,PIL一般是anaconda自带的,cv2是opencv的python版本。base64在网络传输图片的时候经常用到。 ##PIL读取、保存图片方法 from PIL import Image img = Image.open(img_path) img.save(img_path2) 1. 2. 3.
PIL.Image转换成OpenCV格式：import cv2 from PIL import Image import numpy image = Image.open("plane.jpg")image.show()img = cv2.cvtColor(numpy.asarray(image),cv2.COLOR_RGB2BGR)cv2.imshow("OpenCV",img)cv2.waitKey()以上这篇Python 实现OpenCV格式和PIL.Image格式互转就是⼩编分享给⼤家的全部...
