Filing Date: 2004-04-06
Classification: G06T

Abstract:
A system for determining an assigned classification for a set of physical events on a substrate, the system comprising:sensors for sensing the physical events on the substrate and for producing event data, a plug in rule module manager for receiving and managing any number of plug in rule modules, at least one plug in rule module, each plug in rule module having, an input for receiving the event data, the input also for receiving confidence values from preceding plug in rule modules, a local filter for analyzing the received confidence values from the preceding plug in rule modules and selectively by passing the plug in rule module based at least in part upon the received confidence values from the preceding plug in rule modules, an analyzer for analyzing the event data in view of a given classification associated with the plug in rule module, and for assigning a confidence value based at least in part upon how well the event data fits the given classification, and an output for providing the confidence value to subsequent plug in rule modules, and a post processor for receiving the confidence values provided by the at least one plug in rule module, and for making a final selection of the assigned classification to be associated with the set of physical events from the given classifications based at least in part upon a comparison of the confidence values produced by all plug in rule modules.
