About the Author
Joseph Howse might be at home right now, sitting on a sofa and writing
a book, or he might have dashed away with a suitcase full of books,
cameras, and computers. 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.
