About image-comparison-tool

A command-line tool for comparing images through similarity scores and visualized differences. It supports individual pairs and batch comparisons, with heatmaps and threshold detection for changed areas.

Key features

  1. 01SSIM similarity scoring
  2. 02Pixel difference highlighting
  3. 03Side-by-side image layout
  4. 04Color-coded difference heatmaps
  5. 05Batch image-pair comparison
  6. 06Significant-change detection

Use cases

  1. 01Reviewing before-and-after images
  2. 02Finding visual changes in image batches
  3. 03Checking whether image differences exceed a threshold
