CSS Recognizer

Your droid will be able to learn shapes and objects from its surroundings.

Source code now available on GitHub: https://github.com/xiegeo/cssr

- How does it work?

The app will start not knowing anything. For your droid to learn, it will require much help from you. You will teach it shapes for it to match. The matching algorithm used is Curvature Scale Space, hence the name CSS Recognizer.

- How to Use

Play around with the camera, you should be able to find objects, such as toys, symbols, or hand gestures, that the app selects with little to no artifacts. The object can be anything that fits inside the view of the camera. Complex backgrounds, backgrounds with colors similar to the object, shades, and highlights might confuse the selection algorithm.

Once the app finds a good selection, click on the center of the screen and teach it the name of the object or the name of the shape. Find other objects and repeat.

Point your camera back to a learned object, now the app should tell you what it is. If it does not, just teach it the intended name again for reinforcement.
