Image data compression involving sub-sampling of luma and chroma values
Abstract:
Chroma values in image data may be sub-sampled, thereby obtaining sub-sampled chroma values. The sub-sampled chroma values may be compressed, thereby obtaining compressed, sub-sampled chroma values. Luma values in the image data may be compressed, thereby obtaining sub-sampled luma values. Edge information for the luma values that are discarded as part of the luma sub-sampling operation may be determined.
Abstract(Chinese):

可以对图像数据中的色度值进行子采样，从而获得次采样色度值。 子采样色度值可以被压缩，从而获得压缩的亚采样色度值。 可以压缩图像数据中的亮度值，从而获得子采样亮度值。 可以确定作为亮度子采样操作的一部分而被丢弃的亮度值的边缘信息。
