I'm looking for a way to detect a specific object: my keyboard (it's a project of virtual reality with your keyboard displayed at the correct location in the virtual world).
Discovering the Traincascade module, I'm aware it's easy to detect faces but you have to train Opencv to detect any other thing. And the procedure is quite long, take some computer power, with a right choice of pictures...
During my research, I've already found xml files (the final product of the traincascade training) to detect cars.
Is there some way to find already-made xml files for any objects (as a keyboard for my problem)? Or a project of database of this kind?
