Abstract
Official abstract text for this publication.
A method for performing indexing in an image decoder. The method includes identifying a tile in an image, wherein the image comprises a plurality of tiles, and wherein each tile includes color data associated with a plurality of pixels. The method includes asymmetrically providing a plurality of indices throughout the tile. The method includes identifying a pixel in the tile. The method also includes determining a corresponding rectangular grid that includes the pixel, wherein the corresponding rectangular grid comprises at least one indices in a group of indices. The method includes determining an index for the pixel by bilinearly filtering the group of indices that is associated with the corresponding rectangular grid, wherein the filtering is performed in relation to the pixel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for indexing as executed by an image decoder of a processor, comprising: identifying a tile in an image, wherein said image comprises a plurality of tiles, wherein each tile includes color data associated with a plurality of pixels; asymmetrically providing a plurality of indices throughout said tile; identifying a pixel in said tile; determining a corresponding rectangular grid including said pixel, wherein said corresponding rectangula…
