Dive deeper into each OCR engine's capabilities, strengths, and limitations
Tesseract is one of the most popular open-source OCR engines, developed by Google. It's been in development since the 1980s and has undergone significant improvements over time, especially with the introduction of LSTM neural networks in version 4.
Tesseract processes pages at approximately 300 milliseconds per page for standard documents, making it one of the fastest OCR solutions available. This speed makes it ideal for real-time applications and batch processing of large document sets.
With an accuracy rate of 85-90% on clear, well-formatted text, Tesseract performs well on printed documents but struggles with handwriting, complex layouts, and low-quality images. Its accuracy drops significantly with poor-quality scans or images with noise.
