Methods and apparatus for palette coding
A method and apparatus for palette coding to permit the encoding and decoding of a video sequence using a chroma palette and a luma palette include determining that a luma color plane and a chroma color plane have different split tree structures. A luma palette is generated by associating a set of luma indices with a set of luma values. A chroma palette is generated by by associating a set of chroma indices with a first set of chroma values and a second set of chroma values. A set of samples of the video sequence is coded using the chroma palette and the luma palette.
