Overview of this book

Computer vision is found everywhere in modern technology. OpenCV 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 OpenCV 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 OpenCV 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 OpenCV and their actual implementation. By the end of this book, you will have acquired the skills to use OpenCV and Python to develop real-world computer vision applications.

In this chapter, you learned the concept of ANN. You also learned that one of its uses within the field of object recognition is the implementation of MLP, including the advantages and disadvantages of MLP against other machine learning strategies, such as SVM. Regarding ANN-MLP, you learned which layers form its structure and how to define and implement them to build an image classifier and then learned how to evaluate an MLP, training its robustness and accuracy.  And in the last section, we implemented an example of an MLP to detect an object in an unknown image.

Remember that the world of computer vision is filled with endless possibilities! This book is designed to teach you the necessary skills to get started on a wide variety of projects. Now it's up to you and your imagination to use the skills you have acquired here to build something unique and interesting.
