OpenCV, arguably the most widely used computer vision library, includes hundreds of ready-to-use imaging and vision functions used in both academia and industry. It mainly focuses on real-time image processing. As cameras get cheaper and imaging features grow in demand, the range of applications using OpenCV increases significantly, both for desktop and mobile platforms.

The book provides an example-based tour of OpenCV's main modules and algorithms, including the latest available in version 3.0. Starting with the setup and description of the library, this book teaches you how to add graphical user interface capabilities to OpenCV programs. Further, you will learn about the essential techniques such as image processing, image segmentation, object detection, and motion, which will help you process and analyze images better. You will also learn how to extract 2D features from images and how to take advantage of machine learning. By the end of this book, you will completely understand how to put those computer vision techniques into practice.


  • Create OpenCV programs with a rich user interface
  • Develop real-world imaging applications using free tools and libraries
  • Understand the intricate details of OpenCV and its implementation using easy-to-follow examples

Oscar Deniz Suarez

Oscar Deniz Suarez's research interests are mainly focused on computer vision and pattern recognition. He is the author of more than 50 refereed papers in journals and conferences. He received the runner-up award for the best PhD work on computer vision and pattern recognition by AERFAI and the Image File and Reformatting Software Challenge Award by Innocentive Inc. He has been a national finalist for the 2009 Cor Baayen award. His work is used by cutting-edge companies, such as Existor, Gliif, Tapmedia, E-Twenty, and others, and has also been added to OpenCV. Currently, he works as an associate professor at the University of Castilla-La Mancha and contributes to VISILAB. He is a senior member of IEEE and is affiliated with AAAI, SIANI, CEA-IFAC, AEPIA, and AERFAI-IAPR. He serves as an academic editor of the PLoS ONE journal. He has been a visiting researcher at Carnegie Mellon University, Imperial College London, and Leica Biosystems. He has coauthored two books on OpenCV previously.

Jesus Salido Tercero

Jesus Salido Tercero gained his electrical engineering degree and PhD (1996) from Universidad Politécnica de Madrid (Spain). He then spent 2 years (1997 and 1998) as a visiting scholar at the Robotics Institute (Carnegie Mellon University, Pittsburgh, USA), working on cooperative multirobot systems. Since his return to the Spanish University of Castilla-La Mancha, he spends his time teaching courses on robotics and industrial informatics, along with research on vision and intelligent systems. Over the last 3 years, his efforts have been directed to develop vision applications on mobile devices. He has coauthored a book on OpenCV programming for mobile devices.

Mª del Milagro Fernández Carrobles

Mª del Milagro Fernández Carrobles received her Bachelor's degree in Computer Science and Master's degree in Physics and Mathematics from the University of Castilla-La Mancha, Spain, in 2010 and 2011, respectively. She is currently a PhD candidate and works at Visilabs. Her research interests include image processing and artificial intelligence, especially in medical imaging.

Noelia Vállez Enano

Noelia Vállez Enano has liked computers since her childhood, though she didn't have one before her mid-teens. In 2009, she finished her studies in computer science at the University of Castilla-La Mancha, where she graduated with top honors. She started working at the VISILAB group through a project on mammography CAD systems and electronic health records. Since then, she has obtained a master's degree in physics and mathematics and has enrolled for a PhD degree. Her work involves using image processing and pattern recognition methods. She also likes teaching and working in other areas of artificial intelligence.

Ismael Serrano Gracia

Ismael Serrano Gracia received his degree in computer science in 2012 from the University of Castilla-La Mancha. He got the highest marks for his final degree project on person detection. This application uses depth cameras with OpenCV libraries. Currently, he is a PhD candidate at the same university, holding a research grant from the Spanish Ministry of Science and Research. He is also working at the VISILAB group as an assistant researcher and developer on different computer vision topics.

Julio Alberto Patón Incertis

Julio Alberto Patón Incertis graduated from the University of Castilla-La Mancha. He started developing computer vision applications as part of his Master's degree project in Computer Science. He has focused on mobile devices, mainly Android; he has created a mobile application for this platform that is capable of locating, tracking, and recognizing text for blind people. This application was later used as a part of a patent-pending indoor positioning system. OpenCV has been an essential part of all his projects.
