Image Recognition
In 2008 we used a camera to identify the opposite keeper, the walls and the goal. Because this was a novelty for RoboCupJunior teams we put a paper together and presented at at the symposium at the World Championship 2008 in Suzhou, China.
The paper is published under L. Iocchi et al. (Eds.): RoboCup 2008, LNAI 5399, pp. 308–317, 2009. (c) Springer-Verlag Berlin Heidelberg 2009. Springer's LNCS
