Tesseract4Delphi

Tesseract4Delphi is a Delphi and Lazarus/FPC component that uses the Tesseract project to recognize text in images (OCR).

Tesseract4Delphi is based in the TTesseractOCR4 project made by Damian Woroch.

The assets\tessdata directory contains the models for several languages. For additional languages and trained models visit the Tessdata repository.

Tesseract4Delphi was developed and tested on Delphi 13, Delphi 6 and Lazarus 4.4/FPC 3.2.2.

Tesseract4Delphi demos have been tested in Windows 10, Windows 11 and Linux Mint 22.3.
