compare-images

Implementation of nine evaluation metrics to access the similarity between two images and obtain the regions of the two input images that differ. The nine metrics are as follows:

• Root mean square error (RMSE),
• Peak signal-to-noise ratio (PSNR),
• Structural Similarity Index (SSIM),
• Feature-based similarity index (FSIM),
• Information theoretic-based Statistic Similarity Measure (ISSM),
• Signal to reconstruction error ratio (SRE),
• Spectral angle mapper (SAM),
• Universal image quality index (UIQ),
• Visual Information Fidelity (VIFP),

Instructions

The following step-by-step instructions will guide you through installing this package and run evaluation using the command line tool.

Note: Supported python versions are 3.6, 3.7, 3.8, and 3.9.

Install package library

pip install image-similarity-measures

python3 -m pip install -r requirements.txt

Usage

Parameters

  --org_img_path FILE_PATH   Path to original input image
  --pred_img_path FILE_PATH  Path to predicted image
  --metric METRIC       select an evaluation metric (fsim, issm, psnr, rmse,
                        sam, sre, ssim, uiq, vifp, all) (can be repeated)

Terminal

python main.py --org_img_path FILE_PATH --pred_img_path FILE_PATH --metric METRIC

Example

python main.py --org_img_path Images/1.png --pred_img_path Images/2.png --metric all
