Admittedly, I am a novice to Computer Vision and picked-up this book in the hope that it would add something to the comprehensive online documentation available for SimpleCV. This book does exactly that and also provides some ideas of the projects you can undertake with this easy to use library. Full Review >

In this book you will dive into the fascinating world of computer vision. One of the building blocks of a lot of interactive installations at your local museums, especially the science museums. The book discusses the basic principles of computer vision using the SimpleCV Python framework. Starting of with a short introduction in computer vision, you dive right away in the framework. Teaching you how can get images and video feeds. An important aspect of computer vision, as without, you won’t have anything to play around with. This chapter “Image Sources” also shortly discuss how you can leverage the Microsoft Kinect. One of these devices which are quite popular nowadays when creating installations due its great specifications and low cost.
After the introductory chapters how to capture images and use the SimpleCV framework and the processing of the captured images by scaling, cropping or morphing images. The important aspects of computer vision as discussed. Such as, lighting, which highly influence the quality of the captured images and overall success. Discussing how to remove ambient light, different lighting techniques and camera calibration. All important to get the most out of it.
In Chapter 6 discusses the basics of image arithmetics, determine difference between two images, using histograms, chroma keying. After all this arithmetics the real fun starts with an introduction in feature detection or pattern recognition. Explaining how to find feature, such as blobs, lines, circles in parts of images to find the parts we are interested in.
In Chapter 9 we looking into ways how to recognise images within images, as suggested in the book. You never will have trouble finding in Waldo in the Where’s Waldo game anymore. More interestingly how to recognize faces using Haar classifiers or the scanning of barcodes. All interesting topics to play with.
Together with an open-source image library such as “Computer Vision Test Videos” (see: http://www.muonics.net/cvMovies) makes it really fun to play with computer vision. Allowing to quickly start on your own project or great interactive installation.
The book is clear and concise and inspired me to try and play with computer vision again since I finished my interaction design degree. A real nice book to get your feet wet in the computer vision world. As the book doesn’t comes with a tsunami of mathematics to gets you started from the beginning. Only one downside that the book doesn’t really come with a image library as mentioned earlier. Full Review >
