       Preface

      The primary goal of this book is to provide a comprehensive treatment to the subject of convolutional neural networks (CNNs) from the perspective of computer vision. In this regard, this book covers basic, intermediate and well as advanced topics relating to both the theoretical and practical aspects.

      This book is organized into nine chapters. The first chapter introduces the computer vision and machine learning disciplines and presents their highly relevant application domains. This sets up the platform for the main subject of this book, “Deep Learning”, which is first defined towards the later part of first chapter. The second chapter serves as a background material, which presents popular hand-crafted features and classifiers which have remained popular in computer vision during the last two decades. These include feature descriptors such as Scale-Invariant Feature Transform (SIFT), Histogram of Oriented Gradients (HOG), Speeded-Up Robust Features (SURF), and classifiers such as Support Vector Machines (SVM), and Random Decision Forests (RDF).

      Chapter 3 describes neural networks and covers preliminary concepts related to their architecture, basic building blocks, and learning algorithms. Chapter 4 builds on this and serves as a thorough introduction to CNN architecture. It covers its layers, including the basic ones (e.g., sub-sampling, convolution) as well as more advanced ones (e.g., pyramid pooling, spatial transform). Chapter 5 comprehensively presents techniques to learn and regularize CNN parameters. It also provides tools to visualize and understand the learned parameters.
