如果你想将转换后的图像保存到文件,可以使用OpenCV的cv2.imwrite函数: python cv2.imwrite('path_to_save_image.jpg', cv2_image) 完整代码示例 以下是一个完整的代码示例,展示了如何将PIL图像转换为cv2图像并显示它: python from PIL import Image import cv2 import numpy as np # 使用PIL加载图像 pil_image...
# 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...
PIL和cv2是Python中两个常用的图像处理库,PIL一般是anaconda自带的,Image.open打开来的是图像格式,cv2是opencv的Python版本,cv2.imread读取出来的是像素格式。 PIL读取、保存图片 #! /usr/bin/env python3#-*- coding:utf-8 -*-#Author : MaYi#Blog : http://www.cnblogs.com/mayi0312/#Date : 2020-09-...
>>> from PIL import Image >>> import cv2 as cv >>> pimg = Image.open('D:\\traffic.jpg') #PIL Image >>> cimg = cv.cv.CreateImageHeader(pimg.size,cv.IPL_DEPTH_8U,3) #CV Image >>> cv.cv.SetData(cimg,pimg.tostring()) >>> cv.cv.NamedWindow('cimg') >>> cv.cv.ShowImag...
1. PIL 与 cv2 相互转化 importcv2fromPILimportImageimportnumpy as np#PIL 转 cv2img= Image.open("test.jpg") img=cv2.cvtColor(np.asarray(img), cv2.COLOR_RGB2BGR)print(type(img))#cv2 转 PILimg = cv2.imread("test.jpg") img=Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))print(...
img = cv2.cvtColor(np.asarray(img), cv2.COLOR_RGB2BGR) plt.subplot(122) plt.imshow(img) plt.show() def CVImageToPIL(path, ): # OpenCV图片转换为PIL image img = cv2.imread(path) img = img[:, :, [2,1,0]] # cv2.imshow("OpenCV",img) ...
img=cv2.imread("plane.jpg")# opencv打开的是BRGcv2.imshow("OpenCV",img)image=Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))image.show()cv2.waitKey() skimage.io.imread io.imread读出图片格式是uint8(unsigned int);value是numpy array;图像数据是以RGB的格式进行存储的,通道值默认范围0-255。
image.show() img = cv2.cvtColor(numpy.asarray(image),cv2.COLOR_RGB2BGR) cv2.imshow("OpenCV",img) cv2.waitKey() 1. 2. 3. 4. 5. 6. 7. 8. 9. OpenCV转换成PIL.Image格式: import cv2 from PIL import Image import numpy img = cv2.imread("plane.jpg") ...
1,使用cv2转换色彩的方法 import numpy as np import cv2 def pil2cv(PIL_image): ''' PIL型 -> OpenCV型 ''' cv2_image = np.array(PIL_image, dtype=np.uint8) if cv2_image.ndim == 2: # 黑白 pass elif cv2_image.shape[2] == 3: # 彩色的3通道 ...
PIL.Image.open读⼊的是RGB顺序,⽽opencv中cv2.imread读⼊的是BGR通道顺序。cv2.imread会显⽰图⽚更蓝⼀些。cv2.imread(path,读取⽅式)⽅法 第⼀个参数是图⽚的路径。第⼆个参数是读取⽅式:cv2.IMREAD_COLOR:读⼊⼀副彩⾊图⽚;cv2.IMREAD_GRAYSCALE:以灰度模式读⼊图⽚;...
