Mastering OpenCV 3

Practical Computer Vision Projects

About This Book

• Updated for OpenCV 3, this book covers new features that will help you unlock the full potential of OpenCV 3
• Written by a team of 7 experts, each chapter explores a new aspect of OpenCV to help you make amazing computer-vision aware applications
• Project-based approach with each chapter being a complete tutorial, showing you how to apply OpenCV to solve complete problems

Who This Book Is For

This book is for those who have a basic knowledge of OpenCV and are competent C++ programmers. You need to have an understanding of some of the more theoretical/mathematical concepts, as we move quite quickly throughout the book.

What You Will Learn

• Execute basic image processing operations and cartoonify an image
• Build an OpenCV project natively with Raspberry Pi and cross-compile it for Raspberry Pi.text
• Extend the natural feature tracking algorithm to support the tracking of multiple image targets on a video
• Use OpenCV 3's new 3D visualization framework to illustrate the 3D scene geometry
• Create an application for Automatic Number Plate Recognition (ANPR) using a support vector machine and Artificial Neural Networks
• Train and predict pattern-recognition algorithms to decide whether an image is a number plate
• Use POSIT for the six degrees of freedom head pose
• Train a face recognition database using deep learning and recognize faces from that database

In Detail

As we become more capable of handling data in every kind, we are becoming more reliant on visual input and what

Daniel Lelis Baggio

Daniel Lelis Baggio started his work in computer vision through medical image processing at InCor (Instituto do Coracao – Heart Institute) in Sao Paulo, where he worked with intravascular ultrasound image segmentation. Since then, he has focused on GPGPU and ported the segmentation algorithm to work with NVIDIA's CUDA. He has also dived into 6degrees of freedom head tracking with a natural user interface group through a project called ehci (http://code.google.com/p/ehci/).He now works for the Brazilian Air Force.

Shervin Emami

Shervin Emami, born in Iran, taught himself electronics and hobby robotics during his early teens in Australia. While building his first robot at the age of 15, he learned how RAM and CPUs work. He was so amazed by the concept that he soon designed and built a whole Z80 motherboard to control his robot, and wrote all the software purely in binary machine code using two push buttons for 0s and 1s. After learning that computers can be programmed in much easier ways such as assembly language and even high-level compilers, Shervin became hooked on computer programming and has been programming desktops, robots, and smartphones nearly every day since then. During his late teens, he created Draw3D (http://draw3d.shervinemami.i nfo/), a 3D modeler with 30,000 lines of optimized C and assembly code that rendered 3D graphics faster than all the commercial alternatives of the time, but he lost interest in graphics programming when 3D hardware acceleration became available. In University, Shervin took a class on Computer Vision and became greatly interested in it. So, for his first thesis in 2003, he created a real-time face detection program based on Eigenfaces, using OpenCV (beta 3) for the camera input. For his master's thesis in 2005, he created a visual navigation system for several mobile robots using OpenCV (v0.96). From 2008, he worked as a freelance Computer Vision Developer in Abu Dhabi and Philippines, using OpenCV for a large number of short-term commercial projects that included: · Detecting faces using Haar or Eigenfaces · Recognizing faces using Neural Networks, EHMM, or Eigenfaces · Detecting the 3D position and orientation of a face from a single photo using AAM and POSIT · Rotating a face in 3D using only a single photo · Face preprocessing and artificial lighting using any 3D direction from a single photo · Gender

David Millan Escriva

David Millan Escriva was 8 years old when he wrote his first program on an 8086 PC with basic language, which enabled the 2D plotting of basic equations. In 2005, he finished his studies in IT through the Universitat Politecnica de Valencia with honors in humancomputer interaction supported by computer vision with OpenCV (v0.96). He had a final project based on this subject and published it on HCI Spanish congress. He participated in Blender, an open source, 3D-software project, and worked on his first commercial movie Plumiferos―Aventuras voladorasas, as a computer graphics software developer. David now has more than 10 years of experience in IT, with experience in computer vision, computer graphics, and pattern recognition, working on different projects and start-ups, applying his knowledge of computer vision, optical character recognition, and augmented reality. He is the author of the DamilesBlog (http://blog.damiles.com), where he publishes research articles and tutorials about OpenCV, Computer Vision in general, and Optical Character Recognition algorithms. David has reviewed the book gnuPlot Cookbook, Packt Publishing, written by Lee Phillips.

Khvedchenia Ievgen

Khvedchenia Ievgen is a Computer Vision expert from Ukraine. He started his career with research and development of a camera-based driver assistance system for Harman International. He then began working as a computer vision consultant for ESG. Nowadays, he is a self-employed developer focusing on the development of augmented reality applications. Ievgen is the author of the Computer Vision Talks blog (http://computer-vision-talks.com),where he publishes research articles and tutorials pertaining to computer vision and augmented reality.

Jason Saragih

Jason Saragih received his BE in mechatronics (with honors) and PhD in computer science from the Australian National University, Canberra, Australia, in 2004 and 2008, respectively. From 2008 to 2010, he was a Postdoctoral fellow at the Robotics Institute of Carnegie Mellon University, Pittsburgh, PA. From 2010 to 2012, he worked at the Commonwealth Scientific and Industrial Research Organization (CSIRO) as a research scientist. He is currently a senior research scientist at Visual Features, an Australian tech start-up company. Dr. Saragih has made a number of contributions to the field of computer vision, specifically on the topic of deformable model registration and modeling. He is the author of two nonprofit open source libraries that are widely used in the scientific community; DeMoLib and FaceTracker, both of which make use of generic computer vision libraries, including OpenCV.
