MizoOCR

The first OCR model for the Mizo language, developed by MWire Labs.

Model Description

MizoOCR is a fine-tuned TrOCR model for recognizing printed Mizo text, including its unique diacritical characters (â, ê, î, ô, û). It is built on microsoft/trocr-base-printed and trained on 70,000 deduplicated mix of curated + synthetic image-text pairs drawn from a 200k dataset generated by MWire Labs.

Performance

Split	Character Accuracy
Validation	89.61%
Test	90.68%

Training Data

• Total unique samples after deduplication: 102,171
• Training samples: 70,000
• Validation samples: 5,000
• Test samples: 5,000

Usage

from transformers import TrOCRProcessor, VisionEncoderDecoderModel
from PIL import Image

processor = TrOCRProcessor.from_pretrained("MWirelabs/mizo-ocr")
model = VisionEncoderDecoderModel.from_pretrained("MWirelabs/mizo-ocr")

image = Image.open("mizo_text.jpg").convert("RGB")
pixel_values = processor(image, return_tensors="pt").pixel_values
generated = model.generate(pixel_values)
text = processor.tokenizer.decode(generated[0], skip_special_tokens=True)
print(text)

Limitations

• Trained primarily on synthetic data with a small curated dataset; accuracy on real scanned documents may vary
• Optimized for printed text, not handwritten
• Performance may vary on heavily degraded or low-quality images
