Pattern Matching

• Familiarity with manufacturing.
• Experience or interest in programming, in particular C++.

Audience

• Engineers and developers seeking to develop machine vision applications
• Manufacturing engineers, technicians and managers

Pattern Matching is a technique used to locate specified patterns within an image. It can be used to determine the existence of specified characteristics within a captured image, for example the expected label on a defective product in a factory line or the specified dimensions of a component. It is different from "Pattern Recognition" (which recognizes general patterns based on larger collections of related samples) in that it specifically dictates what we are looking for, then tells us whether the expected pattern exists or not.
