CODING OF HIGH DYNAMIC RANGE IMAGES |
摘要 |
<p>A method for encoding a sequence of pictures into a scalable bitstream comprising a first layer and a second layer is disclosed. The method comprises: - encoding (1 0) a first version of the sequence of pictures into the first layer; - reconstructing (12) at least one region of the first version of the sequence of pictures; wherein the method further comprises: - processing (14) the reconstructed at least one region by applying a one-dimensional color Look Up Table independently on each color component of the reconstructed at least one region to get mapped color components and applying a matrix on the mapped color components to get correlated mapped color components; - encoding (1 6) the one-dimensional color Look Up Table(s) and the matrix in the scalable bitstream; and - encoding (1 8) a second version of the sequence of pictures from the processed at least one region into the second layer.</p> |
