将OpenCV图像从BGR格式转换为RGB格式: OpenCV默认使用BGR颜色空间,而PIL使用RGB颜色空间。因此,在转换之前,需要将图像从BGR格式转换为RGB格式。 python rgb_image = cv2.cvtColor(cv_image, cv2.COLOR_BGR2RGB) 使用PIL的Image.fromarray函数将转换后的图像数据转为PIL图像对象: 使用PIL的Image.fromarray()函数,将...
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...

默认是1. 同时OpenCV不支持GIF格式的图片。 二、代码实现[1] 1. skimage与opencv相互转换 from skimage import img_as_float,img_as_ubyte # opencv_to_skimage sk_image = img_as_float(any_opencv_image) # skimage_to_opencv cv_image = img_as_ubyte(any_skimage_image) 2. PIL与opencv的相互转换 ...

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fromPILimportImage img = Image.open(img_path) img.save(img_path3)##cv2读取、保存图片方法importcv2 ...
