This course provides setup instructions for all the relevant software, including package managers, build tools, Python, NumPy, SciPy, OpenCV, OpenNI, and SensorKinect. The setup instructions are tailored for Windows XP or later versions, Mac OS 10.6 (Snow Leopard) or later versions, and Ubuntu 12.04 or later versions. Other Unix-like operating systems should work too if you are willing to do your own tailoring of the setup steps. You need a webcam for the projects described in the course. For additional features, some variants of the project use a second webcam or even an OpenNI-compatible depth camera such as Microsoft Kinect or Asus Xtion PRO.
The hardware requirement being a webcam (or camera device), except for Chapter 2, Hand Gesture Recognition Using a Kinect Depth Sensor , of the 3rd Module which instead requires access to a Microsoft Kinect 3D Sensor or an Asus Xtion.
The course contains projects with the following requirements.
All projects can run on any of Windows, Mac, or Linux, and they require the following software packages:
- OpenCV 2.4.9 or later: Recent 32-bit and 64-bit versions as well as installation instructions are available at http://opencv.org/downloads.html. Platform-specific installation instructions can be found at http://docs.opencv.org/doc/tutorials/introduction/table_of_content_introduction/table_of_content_introduction.html.
- Python 2.7 or later: Recent 32-bit and 64-bit installers are available at https://www.python.org/downloads. The installation instructions can be found at https://wiki.python.org/moin/BeginnersGuide/Download.
- NumPy 1.9.2 or later: This package for scientific computing officially comes in 32-bit format only, and can be obtained from http://www.scipy.org/scipylib/download.html. The installation instructions can be found at http://www.scipy.org/scipylib/building/index.html#building.
wxPython 2.8 or later: This GUI programming toolkit can be obtained from http://www.wxpython.org/download.php. Its installation instructions are given at http://wxpython.org/builddoc.php.
In addition, some chapters require the following free Python modules:
- SciPy 0.16.0 or later: This scientific Python library officially comes in 32-bit only, and can be obtained from http://www.scipy.org/scipylib/download.html. The installation instructions can be found at http://www.scipy.org/scipylib/building/index.html#building.
- matplotlib 1.4.3 or later: This 2D plotting library can be obtained from http://matplotlib.org/downloads.html. Its installation instructions can be found by going http://matplotlib.org/faq/installing_faq.html#how-to-install.
- libfreenect 0.5.2 or later: The libfreenect module by the OpenKinect project (http://www.openkinect.org) provides drivers and libraries for the Microsoft Kinect hardware, and can be obtained from https://github.com/OpenKinect/libfreenect. Its installation instructions can be found at http://openkinect.org/wiki/Getting_Started.
Furthermore, the use of iPython (http://ipython.org/install.html) is highly recommended as it provides a flexible, interactive console interface.
