This package contains an OCR engine - libtesseract and a command line program - tesseract.
Tesseract 4 adds a new neural net (LSTM) based OCR engine which is focused on line recognition, but also still supports the legacy Tesseract OCR engine of Tesseract 3 which works by recognizing character patterns. Compatibility with Tesseract 3 is enabled by using the Legacy OCR Engine mode (--oem 0).
It also needs traineddata files which support the legacy engine, for example those from the repository.
The NVIDIA® CUDA® Toolkit provides a development environment for creating high-performance, GPU-accelerated applications. With it, you can develop, optimize, and deploy your applications on GPU-accelerated embedded systems, desktop workstations, enterprise data centers, cloud-based platforms, and supercomputers. The toolkit includes GPU-accelerated libraries, debugging and optimization tools, a C/C++ compiler, and a runtime library.
Julia is a high-level, high-performance, dynamic programming language. While it is a general-purpose language and can be used to write any application, many of its features are well suited for numerical analysis and computational science.
A developer CLI that accelerates the time it takes for you to get started on Azure. The Azure Developer CLI (azd) provides a set of developer-friendly commands that map to key stages in your workflow - code, build, deploy, monitor, repeat.
Gitleaks is a SAST tool for detecting and preventing hardcoded secrets like passwords, api keys,
and tokens in git repos. Gitleaks is an easy-to-use, all-in-one solution for detecting secrets,
past or present, in your code.
A vulnerability scanner for container images and filesystems. Easily install the binary to try it out.
Works with Syft, the powerful SBOM (software bill of materials) tool for container images and filesystems.
Godot Engine is a feature-packed, cross-platform game engine to create 2D and 3D games from a unified interface.
It provides a comprehensive set of common tools, so that users can focus on making games without having to
reinvent the wheel. Games can be exported with one click to a number of platforms, including the major desktop
platforms (Linux, macOS, Windows), mobile platforms (Android, iOS), as well as Web-based platforms and consoles.
Syft is a powerful and easy-to-use open-source tool for generating Software Bill of Materials (SBOMs) for container images and filesystems. It provides detailed visibility into the packages and dependencies in your software, helping you manage vulnerabilities, license compliance, and software supply chain security.

Tesseract has unicode (UTF-8) support, and can recognize more than 100 languages "out of the box".
Tesseract supports various output formats: plain text, hOCR (HTML), PDF, invisible-text-only PDF, TSV, ALTO and PAGE.
You should note that in many cases, in order to get better OCR results, you'll need to improve the quality of the image you are giving Tesseract.
This project does not include a GUI application. If you need one, please see the 3rdParty documentation.
Tesseract can be trained to recognize other languages.
See Tesseract Training for more information.
Brief history
Tesseract was originally developed at Hewlett-Packard Laboratories Bristol UK and at Hewlett-Packard Co, Greeley Colorado USA between 1985 and 1994, with some more changes made in 1996 to port to Windows, and some C++izing in 1998. In 2005 Tesseract was open sourced by HP. From 2006 until November 2018 it was developed by Google.
Major version 5 is the current stable version and started with release
5.0.0 on November 30, 2021. Newer minor versions and bugfix versions are available from
GitHub.
Developers can use libtesseractC or
C++ API to build their own application. If you need bindings to libtesseract for other programming languages, please see the
wrapper section in the AddOns documentation.
Documentation of Tesseract generated from source code by doxygen can be found on tesseract-ocr.github.io.
Please report an issue only for a bug, not for asking questions.

Tesseract uses Leptonica library
for opening input images (e.g. not documents like pdf).
It is suggested to use leptonica with built-in support for zlib,
png and
tiff (for multipage tiff).

Premake is a command line utility which reads a scripted definition of a software project, then uses it to perform build configuration tasks or generate project files for toolsets like Visual Studio, Xcode, and GNU Make. Premake's scripts are little Lua programs, so the sky's the limit!
