Overview of this book

Open CV is a cross-platform, free-for-use library that is primarily used for real-time Computer Vision and image processing. It is considered to be one of the best open source libraries that helps developers focus on constructing complete projects on image processing, motion detection, and image segmentation. Whether you are completely new to the concept of Computer Vision or have a basic understanding of it, this book will be your guide to understanding the basic OpenCV concepts and algorithms through amazing real-world examples and projects. Starting from the installation of OpenCV on your system and understanding the basics of image processing, we swiftly move on to creating optical flow video analysis or text recognition in complex scenes, and will take you through the commonly used Computer Vision techniques to build your own Open CV projects from scratch. By the end of this book, you will be familiar with the basics of Open CV such as matrix operations, filters, and histograms, as well as more advanced concepts such as segmentation, machine learning, complex video analysis, and text recognition.

Installing Tesseract OCR on your operating system

Tesseract is an open source OCR engine originally developed by Hewlett-Packard Laboratories, Bristol and Hewlett-Packard Co. It has all the code licenses under the Apache License and is hosted on GitHub at

It is considered one of the most accurate OCR engines that is 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 are lots of Linux distributions, we will not teach you how to install on this operating system.

Normally, Tesseract offers installation packages in your package repository, so before you compile Tesseract, just search there.

Installing Tesseract on Windows

Although Tesseract is hosted on GitHub, its latest Windows installer is still available in the old repository on Google Code. The latest installer version is 3.02.02, and it's recommended that you...
