I'd first like to thank God for all the opportunities He has given me as well as for giving me our happy family.

I'd certainly like to thank Professor Sergio Furuie for introducing me to this wonderful world of computer vision. I'd also like to thank Professor Carlos Henrique Forster for his courses on the subject.

A big thanks goes to all the reviewers of this book, who took their time to put constructive and interesting corrections to its contents.

I would also like to thank the people from Packt Publishing—especially Parag Topre, Nikhil Potdukhe, Sriram Neelakantan, Harsha Bharwani, Sageer Parkar, and Nadeem Bagban—without whom, this book would never have been finished. I would also like to thank them for their patience.

I would like to thank my parents, who brought me into this world and educated me. I also thank my brother for always being there for me.

I dedicate this book to my children, who will always be part of my heart.

I'd also like to thank my wife for supporting me day and night in our life's journey.
