Mastering OpenCV 4 with Python

Section 1: Introduction to OpenCV 4 and Python

In this first section of the book, you will be introduced to the OpenCV library. You will learn how to install everything you need to start programming with Python and OpenCV. Also, you will familiarize yourself with the general terminology and concepts to contextualize what you will learn, establishing the foundations you will need in order to grasp the main concepts of this book. Additionally, you will start writing your first scripts in order to get to grips with the OpenCV library, and you will also learn how to work with files and images, which are necessary for building your computer vision applications. Finally, you will see how to draw basic and advanced shapes using the OpenCV library.

Key benefits

  • Develop your computer vision skills by mastering algorithms in Open Source Computer Vision 4 (OpenCV 4) and Python
  • Apply machine learning and deep learning techniques with TensorFlow and Keras
  • Discover the modern design patterns you should avoid when developing efficient computer vision applications

Description

OpenCV is considered to be one of the best open source computer vision and machine learning software libraries. It helps developers build complete projects in relation to image processing, motion detection, or image segmentation, among many others. OpenCV for Python enables you to run computer vision algorithms smoothly in real time, combining the best of the OpenCV C++ API and the Python language.In this book, you'll get started by setting up OpenCV and delving into the key concepts of computer vision. You'll then proceed to study more advanced concepts and discover the full potential of OpenCV. The book will also introduce you to the creation of advanced applications using Python and OpenCV, enabling you to develop applications that include facial recognition, target tracking, or augmented reality. Next, you'll learn machine learning techniques and concepts, understand how to apply them in real-world examples, and also explore their benefits, including real-time data production and faster data processing. You'll also discover how to translate the functionality provided by OpenCV into optimized application code projects using Python bindings. Toward the concluding chapters, you'll explore the application of artificial intelligence and deep learning techniques using the popular Python libraries TensorFlow, and Keras.By the end of this book, you'll be able to develop advanced computer vision applications to meet your customers' demands.

I am an Electronic Engineer but not a specialist in image processing. I purchased the book because know I need to work on image processing applied to some branches of research in electrical Engineering. I did really like the book since it is practical and accessible. It is possible to get introduced in the field of image processing as well as to dive into more complex applications including machine learning. The use of Python combined with examples makes the learning curve fast, and the reader can choose the level of the depth or the field of application more suitable to his/her needs.Therefore, I think this book can be used by anyone with a very basic knowledge of image processing or someone with expertise in the field that wants to get practical information for any specific field. I do recommend it.

Queria tener un libro que hablase de OpenCV 4.0 y este es sencillamente genial, esta estructurado de una manera correcta, con un avance en el temario que hace que sea muy facil su lectura. Ne gusta su maquetacion, contenido... espero que su autor se aventure a escribir mas obras relacionadas. Me parece muy recomendable.

Very good book. I immediately downloaded all code, so I can see how it works.Very good explanation inside book text + WORKING CODE, that shows in OpenCV and Matplotlib - Images, Histograms - RGB and Gray, binarization, Thresholding methods and results + face detecting and deep learning with OpenCV, TensorFlow etc. If you are starter - highly recommend.

I highly recommend this book especially if you have no experience with OpenCV. I bought this book to help with my capstone project for Computer Science. It has tons of insight and tries to work into ideas based on previous chapters. I was disappointed that it only uses PreTrained models for deep learning, but you can't expect everything in one book.
