Paper Abstract

This paper describes a robust car identification system for surveillance of parking lot entrances that runs completely on a stand alone low cost intelligent camera. In order to meet accuracy and speed requirements hierarchical classifiers and coarse to fine search techniques are applied at each recognition stage from localization, segmentation to classification. The paper gives an overview of the applied image processing techniques and focuses in particular on the character classification part. Character recognition is based on a convolutional neural network that proved to generalize better than a fully connected multi-layer perceptron.
