Distortion metrics can be found here.
Large images were first encoded with BPG at q24 filesizes. Medium is 60% of Large. Small is 60% of Medium. Tiny is 60% of Small. All other codecs were matched to +/- 5% filesize.
All the pictures have been compressed from RGB PNGs.
This study compares 5 differents encoders:
The Python scripts used to generate the compressed images are available on the GIT repository. The configuration file containing the codec settings is recipes.json.
