Pattern Matching Software for Machine Vision Applications

The first step of pattern matching always includes a learning process. A “gold” master is used to create a template. This template is used for identification purposes on all subsequent parts. A score is generated depending on how well the object or feature under inspection matches the original template. You can take advantage of pattern matching in applications that include alignment, gauging, and inspection, as reported in “PCBased Software for Pattern, Color, and Color Pattern Matching”, Photonics Tech Briefs (only in select issues of NASA Tech Briefs), June 2003, page 10a.
