Method for recognizing content in an image sequence
First Claim
1. 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.

Abstract
A method for recognizing content in an image sequence is provided, the method includes the steps of: detecting at least one face appearing in at least one frame of an image sequence under test; recognizing characteristic features of the at least one face; comparing the characteristic features to known features of characters stored in a database, thereby deciding 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 and at least one relation between the appearance of the known character and the at least one additional feature; and comparing the at least one relation to metadata comprising known relations stored in the database each one assigned to a particular known image sequence, thereby recognizing if the image sequence under test at least partially equals one of the known image sequences.

27. 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; detecting and recognizing at least one relation between the determined known character and the at least one additional feature; and comparing the at least one relation to metadata comprising known 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, wherein the detecting at least one face is carried out on a client computer following an attempt to upload the image sequence under test to a server and wherein the upload is denied if the image sequence under test is recognized as copyrighted, 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.

28. A method for recognizing content in an 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 frames of an image sequence under test; detecting and recognizing two or more characteristic features of the at least one face; storing the characteristic features in a database and assigning them to 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; storing the at least one spatial relation to metadata in the database; and assigning the at least one spatial relation to the image sequence under test in the database; 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.
