About:
DSSIM is a high-performance Rust library and command-line tool that calculates the structural similarity index (SSIM) between two images. Unlike traditional metrics like PSNR, SSIM better approximates human visual perception by comparing local patterns of pixel intensities. It supports RGBA images and is optimized for speed, making it suitable for large-scale image comparison tasks.
Key Features:
  • Rust-based implementation for memory safety and speed
  • Perceptual SSIM metric for accurate image quality assessment
  • Supports RGBA images with alpha channel handling
  • Command-line interface for batch processing
Use Cases:
  • Automated image quality testing in CI/CD pipelines
  • Detecting visual regressions in UI or game assets
  • Benchmarking image compression algorithms
Alternatives:
  • imagemagick – General-purpose image processing with SSIM support, but slower and less specialized
  • ssimulacra – Alternative perceptual metric focused on JPEG artifacts, different algorithmic approach
