Abstract

A multi-structure neural network (MSNN) classifier was proposed and applied to classify four varieties (classes) of pistachio nuts. The MSNN classifier consisted of four parallel discriminators (one per class), followed by a maximum selector. Each discriminator was a feed-forward neural network with two hidden layers and a single-neuron output layer. The discriminators were individually trained using physical attributes of the nuts extracted from their images as input. The performance of MSNN classifier was compared with the performance of a multi-layer feed-forward neural network (MLNN) classifier. The average classification accuracy of MSNN classifier was 95.9%, an increase of over 8.9% of the performance of MLNN.
