DocEng_Tessarect_mlt
A fine-tuned Tesseract OCR model for Maltese-language news articles.
Overview
This model was fine-tuned on a synthetic dataset of ~20k PNG image "snippets," each depicting a short excerpt of Maltese text paired with its ground-truth transcription. Training ran for 2000 iterations on top of the base Tesseract Maltese trained data.
Dataset Generation
The synthetic training images were produced in two stages:
Text generation — Maltese news-style text snippets were generated by querying Gemini 3.1 Flash-Lite to generate 120 pdfs covering 10 different topics. The snippets were based on the character set provided in the competition assets and generated predominately in Maltese with some English covering different fonts, text and background colours.
Snippet Extraction - The snippet extraction process scans each individual PDF, identifies text coordinates, and crops specific areas into individual images. The resulting images are saved alongside a CSV index that links each snippet to its corresponding text, and word count. Gaussian blur is applied to 10% of these snippets.
Manual Noising — Randomised manual degradation was implemented.
Usage
Download the trained data file from the Hugging Face Hub and point Tesseract at its containing directory:

from huggingface_hub import hf_hub_download
traineddata_path = hf_hub_download(
repo_id="AlanaBusu/DocEng_Tessarect_mlt",
filename="finetune_tess_extended_2000.traineddata",
)
tessdata_dir = os.path.dirname(traineddata_path)
