Build & run sample projects

Almost every chapter of the book describes a separate project. There are 15 Xcode projects for 17 chapters in the book. Chapter 16 extends the project of Chapter 14, and for Chapter 17 you need only OpenCV source code.

• First of all you will need a computer with Mac OSX and Xcode. An iOS device is also helpful, since not all samples can be executed on Simulator.
• Install OpenCV v2.4.6 or newer. You can go to http://opencv.org, click on Downloads, and download the latest OpenCV framework for iOS. Copy it to the folder with this code.
• Now you can import sample projects to Xcode and run them on Simulator or a real device.

For detailed instructions and explanations please refer to the book.
