Comparison of two images using the structural similarity algorithm (SSIM).
Comparison of two images using the structural similarity algorithm (SSIM). The resulting value varies between 1.0 for identical images and 0.0 for completely different images. It's based on the PIL and also supports GPU acceleration via pyopencl.
python3 -m pip install SSIM-PIL
Be sure to install a working version of pyopencl to benefit from faster parallel execution on the GPU. (The code was tested with OpenCl version 1.2.)
from SSIM_PIL import compare_ssim from PIL import Image image1 = Image.open(path) image2 = Image.open(path) # Compare images using OpenCL by default value = compare_ssim(image1, image2) print(value) # Compare images using CPU-only version value = compare_ssim(image1, image2, GPU=False) print(value)
