Method for compressing a sequence of images comprising a first image and a second image, the method comprising the steps of: generating (102) a first descriptor comprising parameters for displaying a computer-generated graphical element in the first image, the graphical element being of non-photographic origin, and the display parameters not comprising pixel values; processing the second image so as to determine (208) an event which gave rise to a potential variation in the parameters for displaying the graphical element between the first image and the second image; generating (210) a second descriptor comprising an event code indicating the determined event.

Abstract
Method for compressing a sequence of images comprising a first image and a second image, the method comprising the steps of: generating (102) a first descriptor comprising parameters for displaying a computer-generated graphical element in the first image, the graphical element being of non-photographic origin, and the display parameters not comprising pixel values; processing the second image so as to determine (208) an event which gave rise to a potential variation in the parameters for displaying the graphical element between the first image and the second image; generating (210) a second descriptor comprising an event code indicating the determined event.Pubblicazioni consigliate
