Zernike moment invariance in character recognition using artificial neural networks (ANN)

Abstract

A number of researchers have used ANNs with different techniques to recognize invariant patterns (Lee and Oldham (1990), Burr (1988), Khotanzad and Lu (1990). Barnard and Casasent (1991), Widrow, Winter and Baxter (1987). These techniques can be broadly classified as preprocessing the input signal to be invariant to geometrical differences.

Keywords:

• ANN
• backpropagation
• gradient range based heuristic (GRBH)
• learning rates
