Technical requirements

As we saw from the previous chapters, users are required to have at least Qt version 5 installed and some basic knowledge of C++ and Qt programming. Also, the latest version of Tesseract, version 4.0, should be correctly installed, as we will use this library as the OCR facility in this chapter. For Windows, a prebuilt binary package of Tesseract can be found at https://github.com/UB-Mannheim/tesseract/wiki. For UNIX-like systems, we will build Tesseract from the source step by step before we use it.

Some knowledge of deep learning will also be a big help in understanding the content of this chapter.

All the code for this chapter can be found in our code repository at https://github.com/PacktPublishing/Qt-5-and-OpenCV-4-Computer-Vision-Projects/tree/master/Chapter-05.
