将一序列图像编码之方法以及将位元流解码之方法，及其装置;METHOD FOR CODING A SEQUENCE OF PICTURES AND METHOD FOR DECODING A BITSTREAM AND CORRESPONDING DEVICES

摘要

本发明系为一种将一序列图像编码成一可调位元流之方法，该可调位元流包括一第一层及一第二层，该方法包括以下步骤：将该序列图像之一第一版本编码(10)成第一层；重建(12)该序列图像之第一版本之至少一区域；其中该方法尚包括以下步骤：藉由将一单维色彩查找表独立地应用于该至少一重建区域之各色彩分量上以得到数个映射色彩分量，及将一矩阵应用于该等映射色彩分量上以得到数个关联映射色彩分量，以处理(14)该至少一重建区域；将该(等)单维色彩查找表及该矩阵编码(16)至该可调位元流中；及将该序列图像中从该至少一处理过区域来之一第二版本编码(18)成第二层。; 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 (16) the one-dimensional color Look Up Table(s) and the matrix in the scalable bitstream; and encoding (18) a second version of the sequence of pictures from the processed at least one region into the second layer.
