Tesseract OCR

Tesseract OCR is an open-source Optical Character Recognition (OCR) engine that includes a powerful library, libtesseract, and a command line program, tesseract. Designed for developers and data scientists, it leverages advanced neural network technology (LSTM) for line recognition while maintaining compatibility with the legacy Tesseract 3 engine, which recognizes character patterns.

Key features include support for over 100 languages out-of-the-box, Unicode (UTF-8) support, and the ability to process various image formats such as PNG, JPEG, and TIFF. Tesseract can produce multiple output formats including plain text, hOCR (HTML), PDF, invisible-text-only PDFs, TSV, ALTO, and PAGE. Additionally, users can enhance the OCR results by improving image quality and can train Tesseract to recognize additional languages.

This versatile tool is ideal for developers looking to integrate OCR capabilities into their applications or workflows, as well as researchers and organizations needing to convert scanned documents into editable text. Tesseract's open-source nature allows for customization and adaptation, making it a valuable asset in various projects involving text recognition and processing.
