CONTENT-ADAPTIVE APPLICATION OF FIXED TRANSFER FUNCTION TO HIGH DYNAMIC RANGE (HDR) AND/OR WIDE COLOR GAMUT (WCG) VIDEO DATA
摘要:
This disclosure relates to processing video data, including processing video data to conform to a high dynamic range (HDR)/wide color gamut (WCG) color container. The techniques apply, on an encoding side, pre-processing of color values prior to application of a static transfer function and/or apply post-processing on the output from the application of the static transfer function. By applying pre-processing, the examples may generate color values that when compacted into a different dynamic range by application of the static transfer function linearize the output codewords. By applying post-processing, the examples may increase signal to quantization noise ratio. The examples may apply the inverse of the operations on the encoding side on the decoding side to reconstruct the color values.
