Patent ID: 8077930

Claim:
A method for recognizing content in image sequence having at least one image frame, the method comprising the steps of: detecting at least one face appearing in at least one of the image frames of an image sequence under test; detecting and recognizing two or more characteristic features of the at least one face; comparing the characteristic features to known features of characters stored in a database for determining whether the face represents a known character; detecting and recognizing at least one additional feature in at least one frame of the image sequence under test, wherein the at least one additional feature comprises a feature movable independently of the at least one face; detecting and recognizing at least one spatial relation between the determined known character and the at least one additional feature; comparing the at least one spatial relation to metadata comprising known spatial relations stored in the database each one assigned to a particular known image sequence for recognizing if the image sequence under test at least partially equals one of the known image sequences; detecting and recognizing two or more characters in different frames; detecting an appearance of the two or more characters; and detecting and recognizing at least one spatiotemporal relation between the appearance of the two or more characters.
