Abstract

There are increasing needs of personal verification technologies using physical characteristics of humans for automatic gate control systems. In this paper, we propose a personal verification system with hand shapes using a modular-type neural network with RBF output units. We extracted many features from a hand image with a simple algorithm, and then selected 20 features among them based on the results of the statistical analysis. These features are lengths of fingers and the area of a palm, etc. We used a set of the selected features as an input pattern to the modular-type neural network. Each module of the modular-type neural network is a three-layered neural network that has one RBF output unit. The modular-type neural network with RBF output units can achieve high rejection rates on patterns of unlearned classes. This is its advantage over the conventional modular-type neural networks with sigmoidal output units. We show that our system achieves both high verification rates on patterns of 40 learned persons and high rejection rates on patterns of 20 unlearned persons.
