A modular neural network classifier for the recognition of occluded characters in automatic license plate reading

Nijhuis, J A G; Broersma, A and Spaanenburg, Lambert LU (2002) 5th International Conference on Computational Intelligent Systems for Applied Research (FLINS) In COMPUTATIONAL INTELLIGENT SYSTEMS FOR APPLIED RESEARCH : Proceedings of the 5th International FLINS Conference p.363-372
Abstract
Occlusion is the most common reason for lowered recognition yield in free-flow license-plate reading systems. (Non-)occluded characters can readily be learned in separate neural networks but not together. Even a small proportion of occluded characters in the training set will already significantly reduce the overall recognition yield. This paper shows that a modular network can handle a realistic mixture of (non-) occluded characters with a 99.8% recognition yield per character.
