将一张图像与 Cloudinary 存储进行比较

Question

我想将一个文件与 Cloudinary 路径中的完整照片路径进行比较，但我不知道如何做。有人可以帮我吗？

这是我用于本地路径的代码

import cv2
import os
import cloudinary

directory = './images'
upload = cv2.imread("images/img1.jpg")

for entry in os.listdir(directory):

    if entry.lower().endswith( ('.jpg', '.jpeg', '.png', '.gif') ):

        fullname = os.path.join(directory, entry)
        print('fullname:', fullname)
        duplicate = cv2.imread(fullname)

        if upload.shape == duplicate.shape:
            print("The images have same size and channels")

            #difference = cv2.subtract(upload, duplicate)
            #b, g, r = cv2.split(difference) 
            #if cv2.countNonZero(b) == 0 and cv2.countNonZero(g) == 0 and cv2.countNonZero(r) == 0:
            if (upload == duplicate).all():
                print("images are the same")

        else:
            print("images are different")

使用以下代码将给定图像与云存储文件夹中的图像进行比较。我正在按照上面代码中描述的逻辑比较两个图像。

import urllib.request as req 
import cloudinary            # pip install cloudinary

cloudinary.config(
  cloud_name = 'YOUR-CLOUD-NAME',  
  api_key = 'YOUR-CLOUDINARY-API-KEY',  
  api_secret = 'YOUR-CLOUDINARY-API-SECRET-KEY'  
)

# image you want to compare with images present in cloudinary storage folder
image = cv2.imread('sample_image.jpg')
print(image.shape)

for i in cloudinary.Search().expression("folder:your_folder_name").execute()['resources']:
    img_url = cloudinary.CloudinaryImage(i['url']).build_url()
    # sample-url: http://res.cloudinary.com/duutxbavx/image/upload/v1564333096/test/flower3_zj6hqi.jpg

    img_ext = img_url.split('/')[8].split('.')[1]
    req.urlretrieve(img_url, "filename"+img_ext) 

    img = cv2.imread('filename'+img_ext)
    print(img_url,'\n',(img_ext, img.shape))

    if image.shape == img.shape:
        print("The images have same size and channels")

        if (image == img).all():
                print("images are the same")
    else:
        print("images are different")
