Abstract: A system and method for texture decompression is described. The method comprises receiving a first compressed texture block including two or more disjoint subsets of data and decompressing the first compressed texture block. The decompressing includes decompressing the two or more disjoint subsets in the first compressed texture block to form texels. The two or more disjoint subsets include a first disjoint subset comprising a first set of color endpoints and a second disjoint subset comprising a second set of color endpoints.

Abstract: Embodiments of the present invention are directed to a method and apparatus for block based image compression with multiple non-uniform block encodings. In one embodiment, an image is divided into blocks of pixels. In one embodiment the blocks are four pixels by four pixels, but other block sizes are used in other embodiments. In one embodiment, a block of pixels in the original image is compressed using two different methods to produce a first and second compressed block. Thus, each block in the original image is represented by two, typically different, compressed blocks. In one embodiment, color associated with a pixel is determined by combining the compressed information about the pixel in the first compressed block with information about the pixel in the second compressed block. In another embodiment, global information about the image is combined with the information in the first and second compressed blocks.

Abstract translation: 本发明的实施例涉及一种用于具有多个非均匀块编码的基于块的图像压缩的方法和装置。 在一个实施例中，图像被划分成像素块。 在一个实施例中，块是四像素乘四像素，但在其他实施例中使用其他块大小。 在一个实施例中，使用两种不同的方法来压缩原始图像中的像素块以产生第一和第二压缩块。 因此，原始图像中的每个块由两个通常不同的压缩块表示。 在一个实施例中，通过将关于第一压缩块中的像素的压缩信息与关于第二压缩块中的像素的信息组合来确定与像素相关联的颜色。 在另一个实施例中，关于图像的全局信息与第一和第二压缩块中的信息组合。

Abstract: A texture compression method is described. The method comprises splitting an original texture having a plurality of pixels into original blocks of pixels. Then, for each of the original blocks of pixels, a partition is identified that has one or more disjoint subsets of pixels whose union is the original block of pixels. The original block of pixels is further subdivided into one or more subsets according to the identified partition. Finally, each subset is independently compressed to form a compressed texture block.

Abstract: A texture decompression method is described. The method comprises receiving a compressed texture block, determining a partition of pixels used for the compressed texture block, wherein the partition includes one or more disjoint subsets into which data in the compressed texture block is to be unpacked, unpacking data for each subset based on the determined partition, and decompressing each of the one or more disjoint subsets to form an approximation of an original texture block.
