    Abstract: A method for compressing an image includes decomposing the image into one or more regions. A region of the image is selected to be evaluated. The selected region is transformed and quantized if the region does not meet a predetermined compression acceptability criteria. The predetermined compression acceptability criteria may include a specific bit rate, a specific image quality, or combinations thereof. If the region does not meet the predetermined compression acceptability criteria after the region has been transformed and quantized, then the transformation and quantization settings are adjusted and the region is transformed and quantized using the adjusted settings. The region is then encoded when the predetermined compression acceptability criteria has been reached. The encoding may include additional compression stages.

    Abstract translation: 用于压缩图像的方法包括将图像分解成一个或多个区域。 选择图像的区域进行评估。 如果区域不满足预定的压缩可接受性标准，则对所选择的区域进行变换和量化。 预定的压缩可接受性标准可以包括特定比特率，特定图像质量或其组合。 如果该区域已经变换和量化之后该区域不满足预定的压缩可接受性标准，则调整变换和量化设置，并且使用经调整的设置对该区域进行变换和量化。 然后当达到预定的压缩可接受性标准时对该区域进行编码。 编码可以包括额外的压缩级。

    Abstract: A processing unit, method, and medium for decompressing or generating textures within a graphics processing unit (GPU). The textures are compressed with a variable-rate compression scheme such as JPEG. The compressed textures are retrieved from system memory and transferred to local cache memory on the GPU without first being decompressed. A table is utilized by the cache to locate individual blocks within the compressed texture. A decompressing shader processor receives compressed blocks and then performs on-the-fly decompression of the blocks. The decompressed blocks are then processed as usual by a texture consuming shader processor of the GPU.

    Abstract: A method, apparatus, and a non-transitory computer readable medium for compressing an image including one or more regions are presented. An image is decomposed into one or more regions and a region is evaluated to determine whether the region meets a predetermined compressions acceptability criteria. In response to the region not meeting the predetermined compression acceptability criteria, the region is transformed and quantized. The region is then encoded in response to the transformed and quantized region meeting the predetermined compression acceptability criteria. In response to the transformed and quantized region not meeting the predetermined compression acceptability criteria, transformation and quantization settings are adjusted and the region is transformed and quantized using the adjusted settings. The region is then encoded in response to the predetermined compression acceptability criteria having been reached.
