Nonlinear Resistive Grid Wavelet Transformations for Texture Feature Extraction

Abstract

This report describes an analog method to extract gray-scale texture features. This method uses a nonlinear resistive grid to perform a two- dimensional pseudowavelet transform of the initial input image. Texture features are computed using first- and second- order variance estimates of the transform coefficients. Some preliminary results are presented indicating the natural segmentation that the nonlinearity provides at the boundary of two dissimilar textures.
