DEFINITION

Classification: 382/220

Calculating weighted similarity or difference (e.g., don't-care areas):

(under subclass 218) Subject matter wherein certain areas or features that are more important than others are assigned a greater weight or value so that their correspondence with an input pattern* yields a larger output match value; this subclass l so includes using reference pattern*s that have areas that can be of any value and still produce a match, such as don't-care areas.
