Tesseract-Ocr

Tesseract OCR is an open-source optical character recognition engine that converts images of text into machine-readable text. It is maintained through its GitHub repository and relies on external libraries such as Leptonica, which is licensed under the BSD 2-clause license. The tool supports both legacy Tesseract 3 and a new LSTM-based neural network engine introduced in Tesseract 4, which focuses on line-level text recognition. This evolution improves accuracy in extracting text from scanned documents, images, or screenshots. Users include developers and automation tools that require text extraction from non-digital sources. The repository maintains transparency about its dependencies and licensing through its documentation and README files.

Tesseract 4 now includes a new LSTM-based neural network engine focused on line recognition, which improves accuracy in text extraction from images. The GitHub README explicitly notes that Tesseract depends on the Leptonica library, which is licensed under the BSD 2-clause license, indicating ongoing transparency around dependency licensing. The documentation clarifies that both the legacy Tesseract 3 engine and the new LSTM-based engine are supported in Tesseract 4. This dual-engine support suggests continued relevance in automation workflows that require robust text extraction. The repository's README includes build status indicators and a Coverity Scan badge, showing active maintenance. These updates are visible in the source code and documentation, confirming ongoing development activity.
