Document Summary
Step 3 interpretation concerned with recognizing the object: the object in the image is identified by comparing it to predefined. One common technique is template matching, which refers to methods that compare one or more features of an image with corresponding features of a model (template) stored in computer memory. 2d machine vision applications: inspection, part identification, visual guidance and control, safety monitoring. Inspection: mostimportantcategory accountsforabout 90% of all industrial machine vision applications, most applications are in mass production where cost of programming and installation can be spread over many units, typical tasks: Dimensional measurement or gaging verification functions.
