SIGNALING COLOR VALUES FOR 3D LOOKUP TABLE FOR COLOR GAMUT SCALABILITY IN MULTI-LAYER VIDEO CODING |
摘要 |
Techniques are described for signaling information used to generate three-dimensional (3D) color lookup tables for color gamut scalability in multi-layer video coding. A lower layer of video data may include color data in a first color gamut and a higher layer of the video data may include color data in a second color gamut. To generate inter-layer reference pictures, a video encoder or video decoder performs color prediction using a 3D lookup table to convert the color data of a reference picture in the first color gamut to the second color gamut. According to the techniques, a video encoder may encode partition information and/or color values of a 3D lookup table generated for color gamut scalability. A video decoder may decode the partition information and/or color values to generate the 3D lookup table in order to perform color gamut scalability. |
