Method for recognizing content in an image sequence

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.

• 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.
