Abstract
A method and apparatus are provided for encoding an image sequence and outputting a signal having a layered organization with at least a base layer and an enhancement layer. For at least one current image of the sequence, the method includes constructing a hierarchical epitome associated with the enhancement layer corresponding to a maximum resolution level of the current image, using: an epitome associated with the enhancement layer corresponding to the maximum resolution level of the current image; and at least one epitome associated with a preceding layer corresponding to a resolution level lower than the maximum resolution level of the current image.
