Definition: pattern recognition


Identifying an object by its shape or properties. Pattern recognition clearly applies to images; however, it is also used for speech and trends. Virtually any data with repeating values can be identified. The bulk of artificial intelligence (AI) applications deal with pattern recognition. See AI in a nutshell.




Facial Recognition
Before attempting to identify people in a surveillance system, the software may use AI-based pattern recognition to isolate faces (red squares). Such systems may be initially "trained" by feeding them thousands or millions of face samples. See deep learning.
