It’s a relatively easy thing for computers to “see” video, but “computer vision” goes a step further, applying a wide range of techniques by which computers can begin to understand and process the content of a video input. These techniques tend toward the primitive, but they can also produce aesthetically beautiful results. The best place to start with computer vision has long been the standard library, OpenCV. A free (as in beer and freedom) library developed by Intel and with ongoing use in a variety of applications, OpenCV is a terrific, C/C++-based tool not just for things like motion tracking, but video processing in general. OpenCV gets a lot of support in the C++-based

It’s just US$40, and it’s your best ticket to creating your own computer vision and augmented reality projects, imagining stuff before big game console makers do. It’s the Sony PlayStation 3 Eye. Sony intended it to be used with their flagship game console. (The guy working at my local GameStop looked emotionally dejected when I told him I don’t actually own a PS3.) But thanks to community-developed, open-source drivers for all three platforms, the PS3 Eye has become a big choice for interactive applications, from tracking fingers and objects on tables to projection mapping and augmented reality.
