A Spatial Domain Walsh Feature Set,

Abstract

A truncated Walsh Series is utilized as a feature set for chain encoded images. The number of terms used in this series is directly related by an easy to use formula to the number and type of vectors used in the encoded chain and the accuracy desired. The resulting Walsh approximation is shown to form an e-net for the figure thereby preserving the information of the figure while smoothing out possible noisy vectors. A normalization scheme is explained and examples given. (Author)
