G06K 9/00 - Definition fr

Definition statement

This main group covers:

The (computerised) recognition of specific patterns.

General (computerised) recognition functions such as extracting features, clustering, classifying or matching patterns, segmenting images, or separating (signal or image) sources.

Image acquisition specially adapted for specific patterns, e.g. fingerprint or iris sensors.

Image pre-processing, e.g. image thinning, noise filtering.

Means (e.g. specially adapted user interface) for correcting errors produced by computerised pattern recognition; means for assisting humans in presenting patterns (e.g. positioning a finger) for computerised recognition.
