Defect characterization and classification for web materials

The authors describe a development environment for the design and testing of algorithms for automated defect classification in web materials. The environment includes four subsystems: detection, characterization, feature analysis, and classification. A subsystem consists of a number of algorithms from which a specific algorithm is chosen based on the classification objectives. The subsystems are interconnected using direct and feedback loops. The feedback loops are used when evaluating the performance of algorithms in previous subsystems. An example of defect classification is given, including discussion of the results and specific algorithms used by the characterization, feature analysis, and classification subsystems.<>
