He is equipped to "see the world" or at least to do his work in computer vision. He is a software developer at Ad-Dispatch (Canada), where he makes augmented reality games for iOS and Android. Thanks to computer vision, the games can make use of real-world props such as a child's drawings, toys, or blanket-forts. He also provides training and consulting services. He is currently consulting at Market Beat (El Salvador) on an embedded systems project that uses OpenCV for face recognition. He holds three masters degrees in Computer Science, International Development Studies, and Business Administration (Dalhousie University, Canada). His research has been published by ISMAR (International Symposium on Mixed and Augmented Realities), and he would love to meet you there if you go. Android Application Programming with OpenCV is Joe's second book with Packt. His first book, OpenCV Computer Vision with Python, includes an introduction to face tracking and depth cameras (for example, Kinect) on Windows, Mac, and Linux. Joe likes cats, kittens, oceans, and seas. Felines and saline water sustain him. He lives with his multi-species family in Halifax, on Canada's Atlantic coast. I am able to write—and to enjoy writing—because I am constantly encouraged by the memory of Sam and by the companionship of Mom, Dad, and the cats. They are my fundamentals. I am indebted to my editors and reviewers for guiding this book to completion. Their professionalism, courtesy, good judgment, and completion. Their professionalism, courtesy, good judgment, and passion for books are much appreciated.
