An ART network with fuzzy control for image data compression

The application of a simplified ART1 (adaptive resonance theory 1) network with a fuzzy controller to image data compression is presented. The unique feature of a vigilance parameter of ART allows the direct control of the trade-off between compression ratio and image quality; the fuzzy controller can be used to adjust vigilance to seek a better compromise automatically. Furthermore, the decision table of this fuzzy controller is designed to guarantee convergence. Therefore, the network is insensitive to the given initial vigilance values. Simulations are performed, and the results indicate that this fuzzy-control-equipped, simplified ART1 network provides a promising technique for image data compression.<>
