Abstract
Systems, methods, and instrumentalities are disclosed for color space conversion. A video signal associated with a first color space may be received. The first color space may comprise a point. A partition of the first color space that includes the point may be determined. The partition may be associated with a first dimensionality. The point may be converted from the first color space to a second color space using a color space conversion model that corresponds with the partition. The color space conversion model may be associated with a second dimensionality. The second dimensionality may be less than the first dimensionality.
Claims24
A method comprising:
- receiving a video signal associated with a first color space, the first color space comprising a point associated with a color;
- determining a partition of the first color space that includes the point;
- and
- converting the color from the first color space to a second color space having a same number of dimensions as the first color space, using a color space conversion model that corresponds to the partition, wherein a number of dimensions of the color space conversion model is less than a number of dimensions of the partition.
A decoder comprising:
- a processor configured to:
- receive a video signal associated with a first color space, the first color space comprising a point associated with a color;
- determine a partition of the first color space that includes the point, the partition having a number of dimensions;
- and
- convert the color from the first color space to a second color space having a same number of dimensions as the first color space, using a color space conversion model that corresponds with the partition, the color space conversion model having a number of dimensions, wherein a number of dimensions of the color space conversion model is less than a number of dimensions of the partition.
