Tesseract OCR (Optical Character Recognition) engine is a free open-source software developed by Google. It is designed to recognize and extract text from images or scanned documents. Tesseract was initially developed at Hewlett-Packard Laboratories in the 1980s and later released as open source in 2005. Google took over the project in 2006 and has been actively maintaining and improving it since then.

Tesseract has undergone significant improvements over the years and is known for its high accuracy in recognizing printed text. However, its performance may vary depending on the quality of the input image, the complexity of the text, and the language being used.

The Tesseract OCR engine is a powerful tool for extracting text from images and documents. It has gained popularity due to its accuracy, language support, and active development community. However, it's important to note that while Tesseract performs well on printed text, it may not be as effective in recognizing handwriting or text with complex layouts.

Tesseract is an open-source project, which means that its source code is freely available for anyone to use, modify, and distribute. The project has a dedicated community of developers who actively contribute to its development, bug fixes, and feature enhancements.
