meiki.text.recognition.v0
pareto-optimal text recognition model. trained on japanese video games.
meiki.text.recognition achieves state-of-the-art text recognition accuracy as well as latency by redefining "text recognition" as "character detection". the model is a fine-tune of https://github.com/Peterande/D-FINE object detecor combined with a mobilenetv4 CNN backbone. to my knowledge there is no existing, open weight text recognition model with a better accuracy/latency tradeoff for japanese text recognition.
intended use and constraints
- it is specifically trained on japanese video games, therefore performance may vary outside of this use case
- input needs to be resized and padded to be 960x32px
- outputs detection results as characters + bbox + confidence. check the inference.py script for a suggested post processing algorithms
- can detect up to 48 characters
- only works on horizontal text

releases
- 21.02.2026: i released a new version of the checkpoint that should improve accuracy. if you want to use the old one for some reason use this revision: ddd06176a4da56fba082293dbe9898d4e5998af2
