Comparison of two images using the structural similarity algorithm (SSIM).

Project description

SSIM-PIL

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.

Installation

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.)

Usage Example

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)
