Simple image comparison in rust based on the image crate

Note that this crate is heavily work in progress. Algorithms are neither cross-checked not particularly fast yet. Everything is implemented in plain CPU with no SIMD or GPU usage.

Supported now:

  • Comparing grayscale images
    • By RMS - score is calculated by:
    • By MSSIM
      • SSIM is implemented as described on wikipedia:
      • MSSIM is calculated by using 8x8 pixel windows for SSIM and averaging over the results

Planned:

  • Histogram comparisons for grayscale and colored images
  • SIMD for RMS and MSSIM
