Paper Abstract

A real time system for automated rail inspection and flaw classification at speeds up to 25 mph is described. To maintain a fast testing rate, a distributed multiple processor configuration is used for the high speed portion of the system. A graphics computer provides for real time visualization and playback analysis in a modified B-Scan format. A hierarchical approach is used to distribute the total pattern recognition task into a set of stages in which the recognition results at one stage provide input data of the next stage.
