Direct Electronic Transforms for Feature Extraction.

Abstract

A description of a special purpose R and D system for performing direct two-dimensional Walsh transforms of images is described. The system is capable of obtaining 512-squared Walsh coefficients of two-dimensional images in approximately 10 seconds. Successful tests of the system's performance using simple images are also described. (Author)
