Book Description

Dec 25 2014 1449314651 978-1449314651 Second Edition

Learning OpenCV puts you in the middle of the rapidly expanding field of computer vision. Written by the creators of the free open source OpenCV library, this book introduces you to computer vision and demonstrates how you can quickly build applications that enable computers to "see" and make decisions based on that data.

The second edition is updated to cover new features and changes in OpenCV 2.0, especially the C++ interface.

Computer vision is everywhere—in security systems, manufacturing inspection systems, medical image analysis, Unmanned Aerial Vehicles, and more. OpenCV provides an easy-to-use computer vision framework and a comprehensive library with more than 500 functions that can run vision code in real time. Whether you want to build simple or sophisticated vision applications, Learning OpenCV is the book any developer or hobbyist needs to get started, with the help of hands-on exercises in each chapter.

This book includes:

  • A thorough introduction to OpenCV
  • Getting input from cameras
  • Transforming images
  • Segmenting images and shape matching
  • Pattern recognition, including face detection
  • Tracking and motion in 2 and 3 dimensions
  • 3D reconstruction from stereo vision
  • Machine learning algorithms

4.0 out of 5 stars There's is no better OpenCV reference April 9 2009
I purschased this book to help me in using OpenCV for a Block-Based Motion Compensation Application. The first 3 chapters give you all the info you need to learn the core of OpenCV. So I stopped reading at that point since I did not need to use any vision related stuff.

I recommend this book, because there is no other reliable source of information on OpenCV. The OpenCV Wiki is weak and is filled with outdated stuff. The book is not perfect but it help you get the job done.

I also recommend OpenCV, the API is very consistent but not perfect. Once you get used to it you appreciate some of its subtilities.

5.0 out of 5 stars Fantastic reference Jan. 14 2009
Format:Paperback|Verified Purchase
Whether you want to use the OpenCV library in your projects, or just want a good introduction to computer vision, this book is your best bet. It's simple, well written, and fairly comprehensive. I would argue that you would be better off purchasing this book over any theoretical computer vision text if your goal is an introduction to the field.

For example: the explanation of the Kalman filter in this text is far more intelligible than any I've seen elsewhere. It's pretty remarkable - you will have a better understanding of the Kalman filter if you read this text (which documents a computer vision library) than if you read a paper on it! The reason for this is that by necessity there is a strong practical bias in this book, so that the authors can't just throw a wishy-washy formula on the page and hand wave their way around the details. That nuts and bolts level explanation is absolutely essential if you want to get anywhere - whether you're goal is to appy computer vision, or to develop novel algorithms.

Without reservation, I will say that this is the best computer vision book in my library. So in summary, you have to buy this book. You have to buy now. Did you buy it yet?

3.0 out of 5 stars Outdated as of March 2012 March 24 2012
Format:Paperback|Verified Purchase
I bought this book in an attempt to learn openCV. However, almost every example in this book doesn't work with the current version of openCV. The book is good to have a feeling about the workings of openCV, but be prepared to debug the examples in it as it will not work as is.

5.0 out of 5 stars Awesome book, Shipped in Excellent condition Feb. 22 2009
Shipped form Canada to the US. Beat any other price in the US by far.
And the content of the book was better than I hoped.
Looking forward to using OpenCV in my projects.

5.0 out of 5 stars A great guide to OpenCV with plenty of context Oct. 30 2008
By calvinnme - Published on Amazon.com
Format:Paperback|Verified Purchase
This book is excellent at exposing the reader to the various methods available in OpenCV and showing via code examples how to use each one. The author also gives you the website where you can look at the actual source code of each method shown. This is helpful since, for example, if you want to know exactly how the code is going about calculating the Fundamental Matrix, it is difficult to determine this by reading the book alone.

This book would be most useful to someone who already has a fundamental understanding of computer vision and image processing and wants to see how OpenCV will make their programming tasks easier. It does this by coding up well known algorithms into reliable pieces of code that you can use to accomplish more complex tasks. Do not come to this book if you are seeking to learn computer vision. You will only be confused as the author does not offer enough detail to teach you the mathematical foundations. However, I don't think that was his intention at all. Instead it is part user manual, part basic computer vision tutorial and overview, and part idea book. Each chapter is supplemented with excellent and interesting programming exercises that test your knowledge of what has been presented in a practical setting.

For a good basic understanding of computer vision try Computer Vision. To understand the algorithmic underpinnings of 3D computer vision try Introductory Techniques for 3-D Computer Vision. However, before you read either of these you must read Digital Image Processing (3rd Edition), since image processing concepts are fundamental to understanding computer vision tasks. In fact, the two disciplines overlap in many spots. The sad truth of the matter is that no one book will teach you what you need to know to be an effective image scientist. However, this book on OpenCV is essential reading on applying the theory via programming in an effective manner. Highly recommended.

2.0 out of 5 stars Lacking the C++ API Nov. 18 2010
By Peter Harrington - Published on Amazon.com
Format:Paperback|Verified Purchase
I really love OpenCV. I bought this book and read about 50% of it before starting a project. Initially I found some code on the internet that looked like OpenCV code but was lacking pointers and casts. I learned that this clean code is actually C++ code with heavy use of templates in OpenCV 2.0. Sadly the book is based on OpenCV 1.0, so very little of the code in the book is useable.

5.0 out of 5 stars An absolute must have!!! Oct. 20 2008
By Jean-Yves Bouguet - Published on Amazon.com
At last a practical, pragmatic, accessible book on computer vision (and more!) providing step by step guidance on fundamental computational vision topics, with algorithmic explanation (just what is needed!), and concrete example code snippets. This book is now opening the door to the fabulous world of computational vision to anyone. It gives immediate access to a vast collection of image processing, and machine learning functions, all open source!
The book also includes many references and pointers to other material (such as technical papers), allowing the reader to learn more about any topic covered.
This is a great reference book, that won't just sit on your self.

5.0 out of 5 stars This book is GREAT !!! Nov. 12 2008
By Steven Lehar - Published on Amazon.com
Very well written, excellent introduction, beautiful clear figures and illustrations, excellent balance between text, equations, figures, and source code, just the right level of intuitive v.s. technical v.s. mathematical explanation, great explanations of complex algorithmic concepts, with just the right touch of humor here and there to brighten up the dry technical talk, and apparently, a very clear and useful and well designed computer vision software package in that OpenCV, which the author also wrote, with the wonderful advantage that the software is totally free and open source!

2.0 out of 5 stars Great Toolkit, Excruciating Read July 31 2010
By Renner - Published on Amazon.com
The OpenCV library is great and it is nice that somebody put together a book to document it, because the documentation on the opencv wiki is as good as it could be and not well organized. The shortcoming of this book is the extreme verbosity. It is almost excruciating to read because you cannot just skip to the important points because many important points are buried enormous paragraphs that are mostly fluff. The two stars that I give it are entirely for my appreciation of the subject matter.
