Funding entity Indra


INDRA has developed an automatic toll system that is being used in Chile. It is a non-stop toll where cars freely drive on the highway and identifies each car by reading its front license plate. The system is based on a sophisticated set of digital cameras, which produce high quality images of each car, and optical character recognition software, which finds and reads its plate. Although recognition rates are good, accuracy can always been improved after the system has been used for some time, provided that enough amount of data has been gathered.

IIT has experience in image processing, artificial intelligence, and data analysis and will help to detect specific subjects in which the system could be improved. IIT will perform statistical data analysis to evaluate the performance of the current system, and then will apply multifaceted techniques in order to establish which modifications may be more effective improving the accuracy of the system.
