摘要：Described are a system and method to determine the initial luma and chromaphase such that the resulting image after chroma upsampling and scaling has zero phase

difference between the luma and chroma components. Particularly, the describedmethod may include receiving a subsampled input image having luma and chroma values.The method may then perform a phase computation of the input image to determinescaling parameters such that phase differences between all color components of anoutput image are zero. The method may then include performing a combined upscalingand upsampling process on the input image using the scaling parameters to generate anupscaled image with no phase difference from the subsampled image.
