Paper Abstract

A simulation implementing Lateral Subtractive Inhibition (LSI) in a 2D coordinate space was developed providing the means to determine the effects of varying fundamental parameters of the operation. The strength of inhibition between receptors (sensor elements) as a function of distance is variable (the weighting function), as is the absolute size of the neighborhood of receptor interaction. Several different methods of performing the LSI operation were looked at before finding a method that was realizable in a computer simulation. The problems of implementing LSI in software are described in some detail. Application of LSI to a polar-log mapped coordinate system is considered in more than one aspect. The operation can be applied before or after the mapping, with weights dependent on either linear or exponential distances between receptors. The differences between these methods are examined. A set of experiments was devised in order to determine the usefulness of LSI to extract edge and curvature information.
