    • A mechanism is described for facilitating interpolated minimum-maximum compression/decompression for efficient processing of graphics data at computing devices. A method of embodiments, as described herein, includes detecting a tile having pixels representing graphics contents capable of being processed by a graphics processor of a computing device; computing a minimum color value and a maximum color value of the tile. The method may further include splitting the tile into a plurality of interpolation tiles, where each interpolation tile includes a set of pixels of one or more colors. The method may further include computing a plurality of local minimum color values for the plurality of interpolation tiles, computing, based on the plurality of local minimum values, a plurality of residuals for the plurality of interpolation tiles to reduce spreads from the plurality of interpolation tiles, and compressing the reduced plurality of interpolation tiles based on the plurality of residuals.
    • 描述了用于有助于在计算设备处有效处理图形数据的插值最小 - 最大压缩/解压缩的机制。 如本文所述的实施例的方法包括:检测具有表示能够由计算设备的图形处理器处理的图形内容的像素的图块; 计算瓦片的最小颜色值和最大颜色值。 该方法可以进一步包括将瓦片分成多个内插瓦片,其中每个内插瓦片包括一组一个或多个颜色的像素。 该方法可以进一步包括计算多个内插瓦片的多个局部最小颜色值,基于多个局部最小值计算多个内插瓦片的多个残差,以减少来自多个内插瓦片的扩展 ,并且基于所述多个残差来压缩所述缩减的多个内插瓦片。

    • A mechanism is described for facilitating efficient clustering and compression of graphics data at computing devices. A method of embodiments, as described herein, includes detecting a tile having pixels representing graphics contents capable of being processed by a graphics processor of a computing device. The method may further include splitting the tile into a plurality of clusters, where each cluster includes a set of pixels of one or more colors. The method may further include determining a center color for each cluster of the plurality of colors, where determining further includes deciding whether the center color is classified as acceptable for compression. The method may further include compressing contents of one or more of clusters if one or more center colors of the one or more clusters are classified as acceptable.
    • 描述了用于促进计算设备处的图形数据的高效聚类和压缩的机制。 如本文所述的实施例的方法包括检测具有能够由计算设备的图形处理器处理的表示图形内容的像素的图块。 该方法可以进一步包括将瓦片分成多个集群,其中每个集群包括一组一个或多个颜色的像素。 该方法可以进一步包括确定多个颜色的每个簇的中心颜色,其中确定还包括确定中心颜色是否被分类为可接受用于压缩。 该方法还可以包括:如果一个或多个集群的一个或多个中心颜色被分类为可接受,则压缩一个或多个集群的内容。
