Automatic image annotation

Automatic image annotation (also known as automatic image tagging or linguistic indexing) is the process by which a computer system automatically assigns metadata in the form of captioning or keywords to a digital image. This application of computer vision techniques is used in image retrieval systems to organize and locate images of interest from a database. Some annotation engines are online, including the ALIPR.com real-time tagging engine developed by Pennsylvania State University researchers, and Behold.
