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 systems performance using simple images are also described. Author
