It is shown that cellular automata can be used for feature extraction of images in image pattern matching systems. The problem under consideration is an image pattern matching problem of a single image against a database of LEGO bricks. The use of cellular automata is illustrated, and solves this classical content-based image retrieval problem in near… (More)
We consider the realtime content-based image retrieval of LEGO bricks from a database of images of LEGO bricks. This seemingly simple problem contains a number of surprisingly the image signature, and corresponding feature set, and illustrate cellular automaton-based methods for the whole feature extraction phase.
