Un brevet Google publicat recent arata ca motorul de cautare nu numai ca va cauta imagini: in curand, Google va cauta dupa texte IN IMAGINI. Iata un citat:

Extracted image text can also be used to improve image searching. The extracted text can be stored as associated with the particular image for use in generating search results in an image search. Additionally, the extracted image text can be combined with location data and indexed to improve and enhance location-based searching. The extracted text can provide keywords for identifying particular locations and presenting images of the identified locations to a user.

In principiu, acest lucru inseamna ca textul din imagini va fi folosit ca metadata, desi relevanta acestor informatii poate fi relativa. Ganditi-va de exemplu la o poza facuta de niste turisti in Las Vegas, cu toate reclamele in spatele lor…

Google stie deja sa recunoasca fetele, cum e de exemplu iata o cautare de imagini dupa Traian Basescu si inca una cu optiunea &imgtype=face.
