摘要:
A system and method of content adaptive pixel intensity processing are described. The method includes receiving a predefined set of processed video data configured from the processed video data, deriving a range information associated with an original maximum value and an original minimum value for a predefined set of original video data, wherein the predefined set of processed video data is derived from the predefined set of original video data, and adaptively clipping pixel intensity of the predefined set of processed video data to a range deriving from the range information, wherein the range information is incorporated in a bitstream and represented in a form of the original maximum value and the original minimum value, prediction values associated with a reference maximum value and a reference minimum value, or a range index associated with a predefined range set.
