Nikolaus Gradwohl was born in 1976 in Vienna, Austria, and always wanted to become an inventor like Gyro Gearloose. When he got his first Atari, he figured out that being a computer programmer was the closest he could get to that dream. He wrote programs for nearly anything that can be programmed, ranging from an 8-bit microcontroller to mainframes for a living. In his free time, he likes to gain knowledge of programming languages and operating systems.

He is the author of Processing 2: Creative Coding Hotshot, Packt Publishing.

You can see some of his work on his blog at http://www.local-guru.net/.

Luis Díaz Más is a C++ software engineer currently working at Pix4D, where he plays the role of a software architect and develops image processing algorithms that are oriented toward photogrammetry and terrain mapping. He received his PhD in computer science from the University of Cordoba (Spain) that focuses on 3D reconstructions and action recognition. Earlier, he worked for CATEC, a research center for advanced aerospace technologies, where he developed the sensorial systems for UAS (Unmanned Aerial Systems). He has reviewed other OpenCV books published by Packt, and he is continuously looking forward to gaining more knowledge of different topics, such as modern C++ 11/14, Python, CUDA, OpenCL, and so on.

I would like to thank my parents for always supporting me and giving me the freedom to do what I like the most in this life. I would also like to thank my thesis directors, Rafa and Paco, who helped me in my scientific career and from whom I have learned a lot. Finally, a special mention to Celia, the woman who chose to share her life with this software freak and the one who continuously reminds me that there are more things in life apart from programming.
