What is Tesseract OCR?

Tesseract was originally developed at Hewlett-Packard Laboratories Bristol and at Hewlett-Packard Co, Greeley Colorado 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. Since 2006 it is developed by Google.
Tesseract OCR is a tool in the Image Analysis API category of a tech stack.
Tesseract OCR is an open source tool with 34.6K GitHub stars and 6.5K GitHub forks. Here鈥檚 a link to Tesseract OCR's open source repository on GitHub

I use Python because it's a beautiful (both visually and in terms of function) and multi-purpose language. In Paperless, Python is the primary connecting tissue holding all of the parts together: it's the basis of the consumption engine (communicating with Tesseract OCR via pyOCR) and the user-interface (based on Django).

I needed a tool that could convert a rasterised image into text. There are a few out there, but I don't think there's any that match Tesseract OCR for cross-language capability, community support and freedom (it's Free as in freedom and beer).

The setup isn't super-obvious, but once you've got it figured out, all of that can be automated. On top of that, there's lots of programming language-specific libraries out there that'll help plug your stuff into it.

Tesseract OCR Alternatives & Comparisons

What are some alternatives to Tesseract OCR?
TensorFlow
TensorFlow is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.
OpenCV
OpenCV was designed for computational efficiency and with a strong focus on real-time applications. Written in optimized C/C++, the library can take advantage of multi-core processing. Enabled with OpenCL, it can take advantage of the hardware acceleration of the underlying heterogeneous compute platform.
