Why Greek OCR Is Challenging
- Distinguishing Greek letters from visually similar Latin letters (e.g., v/ν, p/ρ, u/υ, x/χ)
- Recognizing monotonic diacritical accents (tonos and dialytika) on lowercase vowels
- Processing historical polytonic Greek texts with breathings and multiple accents
- Handling mathematical and scientific notation mixed with Greek textual content

Tips for Better Greek OCR Accuracy
- Scan at 300 DPI to preserve small vowel accent marks (tonos) and dialytika
- Verify that Greek character representations are not replaced by similar-looking Latin letters in the output
- For polytonic Greek (ancient texts), check breathing marks carefully, as standard OCR defaults to monotonic
Common Use Cases for Greek OCR
- Digitizing Greek legal deeds, notary records, and government gazettes (FEK)
- Extracting text from Greek academic papers, philosophical texts, and scientific studies
- Converting scanned Greek books, publications, and newspaper archives
- Processing Greek invoices, tax forms, and business filings
