To my dearest wife, Inbal, and my daughters, Roni and Noam, for being both my wings and my anchor, and for their incredible ability to know which one of the two I need at any given moment. Thank you, I love you. To my family, Asia, Baruch, Liraz, and Orit, for your endless loving support.

To my wife, Izaskun, my daughter, Eider, and my son, Pau, for their unlimited patience and support at all times. They have changed my life and made it awesome every day. Love you all.  I would like to thank the OpenCV team and community, for this wonderful library, and my coauthors and Packt, for supporting and helping me complete this book.
