Kannada OCR Guide — Extract Text from ಕನ್ನಡ PDFs & Images
Kannada uses rounded characters and an abugida writing system where consonants and vowel signs combine into complex glyphs. These rounded forms and intricate ligatures require OCR trained specifically for Kannada typography.
This guide explains how to extract accurate Kannada text from scanned documents and images while preserving the script's distinctive shapes.
Why Kannada OCR Needs Specialized Handling
Kannada letterforms are rounded, and vowel signs can stack above and below consonants to form complex glyphs.
- Rounded character shapes are unique to Kannada and differ from Telugu.
- Vowel marks (ottakshara) stack above or below consonants.
- Conjunct consonants form complex ligatures.
- Visually similar characters like ಕ/ಗ and ತ/ದ can be confused.
- Mixed Kannada-English documents require script switching.
