Abstract

We examine the performance of several neural network vector quantization (VQ) methods on image coding. The VQ methods we look at are Kohonen's Self-Organizing Feature Map (KSOFM), Frequency-Sensitive Competitive Learning (FSCL), and Self-Creating and Organizing Neural Network (SCONN). We also look at variations of these algorithms by combining different methods. Our simulation results show that the best performance is achieved by the SCONN and the combination KSOFM and FSCL.
