OpenCV 3.x with Python By Example [EPUB ebook] 
Make the most of OpenCV and Python to build applications for object recognition and augmented reality

Computer vision is found everywhere in modern technology. Open CV for Python enables us to run computer vision algorithms in real time. With the advent of powerful machines, we have more processing power to work with. Using this technology, we can seamlessly integrate our computer vision applications into the cloud. Focusing on Open CV 3.x and Python 3.6, this book will walk you through all the building blocks needed to build amazing computer vision applications with ease.
We start off by manipulating images using simple filtering and geometric transformations. We then discuss affine and projective transformations and see how we can use them to apply cool advanced manipulations to your photos like resizing them while keeping the content intact or smoothly removing undesired elements. We will then cover techniques of object tracking, body part recognition, and object recognition using advanced techniques of machine learning such as artificial neural network. 3D reconstruction and augmented reality techniques are also included. The book covers popular Open CV libraries with the help of examples.
This book is a practical tutorial that covers various examples at different levels, teaching you about the different functions of Open CV and their actual implementation. By the end of this book, you will have acquired the skills to use Open CV and Python to develop real-world computer vision applications.
