Overview of this book

OpenCV is one of the best open source libraries available and can help you focus on constructing complete projects on image processing, motion detection, and image segmentation. This Learning Path is your guide to understanding OpenCV concepts and algorithms through real-world examples and activities. Through various projects, you'll also discover how to use complex computer vision and machine learning algorithms and face detection to extract the maximum amount of information from images and videos. In later chapters, you'll learn to enhance your videos and images with optical flow analysis and background subtraction. Sections in the Learning Path will help you get to grips with text segmentation and recognition, in addition to guiding you through the basics of the new and improved deep learning modules. By the end of this Learning Path, you will have mastered commonly used computer vision techniques to build OpenCV projects from scratch. This Learning Path includes content from the following Packt books: •Mastering OpenCV 4 - Third Edition by Roy Shilkrot and David Millán Escrivá •Learn OpenCV 4 By Building Projects - Second Edition by David Millán Escrivá, Vinícius G. Mendonça, and Prateek Joshi

Installing Tesseract OCR on your operating system


Tesseract is an open source OCR engine that was originally developed by Hewlett-Packard Laboratories Bristol and Hewlett-Packard Co. All of its code is licensed under the Apache License and hosted on GitHub at https://github.com/tesseract-ocr. It is considered one of the most accurate OCR engines available: it can read a wide variety of image formats and can convert text written in more than 60 languages. In this session, we will teach you how to install Tesseract on Windows or Mac. Since there's lots of Linux distributions, we will not teach you how to install it on this operating system. Normally, Tesseract offers installation packages in your package repository, so, before compiling Tesseract yourself, just search for it there.

Installing Tesseract on Windows

Tesseract uses the C++ Archive Network (CPPAN) as its dependency manager. To install Tesseract, follow these steps.
