Tamil OCR Guide — Extract Text from தமிழ் PDFs & Images
Tamil is written in a Brahmic abugida with rounded characters, complex vowel signs, and consonant conjuncts. Generic OCR engines built for Latin scripts struggle to segment and recognize these features.
This guide explains how to extract accurate Tamil text from scanned documents and images while preserving the script's unique shapes and combinations.
Why Tamil OCR Needs Specialized Handling
Tamil script combines consonants and vowel signs into glyphs that must be segmented and recognized as a unit.
- Rounded character forms can merge in low-resolution scans.
- Vowel signs (kuril and nedil) attach above, below, or beside consonants.
- Conjunct consonants create complex ligatures.
- The pulli dot distinguishes consonant clusters.
- Documents often mix Tamil with English and other scripts.
