This research project concerns a structured class of vector                     quantizers (VQ) with applications in image and speech source                    coding.  They are called geometric VQ's because they use the                    geometry in N-dimensional space resulting from equipotentials of                the N-th order probability density function.  These structured                  VQ's have greatly reduced implementation complexity compared to                 general or unstructured VQ's, yet their performance can be                      comparable in practical image coding applications.  As a result                 the principal investigator can reasonably look at adaptive                      geometric VQ's with manageable complexity.  It is believed that                 this advancement can be crucial to substantial further                          improvements in VQ and its application to speech and image coding               for the purpose of reduced transmission and storage requirements.
