LV-ROVER ensemble boosts Maltese OCR accuracy by 70%

By PulseAugur Editorial · [2 sources] ·

Researchers have developed LV-ROVER, a novel multi-stream Tesseract voting ensemble designed to improve optical character recognition (OCR) for Maltese, a low-resource language. By building a synthetic training pipeline and a five-stream ensemble, they achieved a 44% improvement in character error rate (CER) compared to a fine-tuned Tesseract baseline. Further post-processing reduced the CER by 70%, demonstrating significant gains in OCR accuracy for Maltese text. AI

IMPACT Improves OCR capabilities for low-resource languages, potentially enabling broader access to digitized text.
