Paper Abstract

We consider two new techniques (wavelets and Gabor transforms) plus morphological methods for use in the detection, image enhancement, and feature extraction stages of scene analysis. We find the new wavelet and Gabor methods to be of potential use for textural/statistical measures that complement other established methods. The optical realization of all methods on a unified optical correlator architecture is noted. The dimensionality problems of the two new methods should be solved by use of linear combination filters (LCFs) of several wavelet or Gabor functions.
