我如何使用 Python 比较两张图像来判断它们是否相似？

Question

I´m working on a project in which I need to compare two images and to say if they are similar, I'm using Python and OpenCV. Somebody know how I can do it?

Answer 1

I've came across a project that required me to compare to images to see if they are similar. I will recommend this Python Lib. Imagehash Go through the documentation to understand how it works.

Here is a sample Code:

from PIL import Image
import imagehash
img0 = imagehash.average_hash(Image.open('img1.jpg')) 
img1 = imagehash.average_hash(Image.open('img2.jpeg')) 
cutoff = 5

if img0 - img1 < cutoff:
  print('images are similar')
else:
  print('images are not similar')

requirements:

pip install ImageHash
pip install pillow
