Why do you need to read this book?
“Why do i need to learn computer vision?” This question has been asked to me countless times in the last few years. When that happens I always proceed with a counter question. Do you want an excellent high paying job? If your answer is yes then you must keep up with technological advances. And If you learn OpenCV you bought a ticket for the future.
Computer vision is an area of artificial intelligence which we use to train the computer to interpret and understand the visual world. It enables machines to see, identify and process images in the same way like humans do. In the last few years there has been a significant progress of computer vision achievements. Nowadays, processing of images is faster and more efficient than ever. Cars, robots, and drones today are able to understand and recognize objects with very high accuracy, almost like humans. And all these technologies today use computer vision in some way or the other.
OpenCV is the most awesome, fascinating and the most popular computer vision library in the world used for all types of image and video analysis. Therefore, the reason why I decided to write a book on this subject is pretty obvious. If you want to start a career in image processing, deep learning, or machine learning, you simply must master computer vision and OpenCV. This book will be an important and beneficial step to achieve that goal.
- Mathematical explanation and theory intuition – Every single line of code needs to be thoroughly understood. There is no point of memorizing and copying the code and not understanding the theory behind it. That is why this book is providing great explanations of algorithms being used in python code.
- Amazing illustrations – It is my belief that any complex mathematical problem can be better understood if it is illustrated properly. That is why this book has many great illustrations that can help you to comprehend these complicated math equations
- Python code – efficient and easy to understand
This book will help you to understand the large number of functions available in the OpenCV library and to learn which function to use in order to solve specific problems.
The book begins with an introduction to computer vision and continues with a step by step explanation of the OpenCV library in Python. Then I take you further through the chapters which are written in such a way that they can be easily understood by beginners with no programming experience. Then, chapters are gradually becoming more and more complex. But don’t worry. If you read a few opening chapters thoroughly you will be able to understand complex mathematical equations and lines of code that seemed so incomprehensible. Each chapter addresses a specific image processing problem and offers a most accurate and productive solution. Furthermore, every task covered in this book contains an extensive both theoretical and mathematical explanation.
What you will learn
First three chapters of this book are written for those who have never written a single line of code in their lives. This is basic OpenCV from scratch using Python which contains some basic operations which are necessary for building your computer vision applications. Here you will learn what is the pixel, how images and videos are represented in a computer and how to manipulate image pixels.
