Why Kannada OCR Is Challenging
- Recognizing the rounded character forms unique to Kannada script which differ from Telugu
- Handling vowel marks (ottakshara) that stack above or below consonants in complex combinations
- Distinguishing visually similar Kannada characters like ಕ/ಗ, ಚ/ಜ, ತ/ದ in small font sizes
- Processing documents mixing Kannada with English, Hindi, or Tulu text
- Correctly segmenting conjunct consonants that form complex ligatures
