An Effective Bicubic Convolution Interpolation-Based Iterative Luma Optimization for Enhancing Quality in Chroma Subsampling [PDF]
Traditionally, prior to compressing an RGB full-color image, for each converted $2\times 2$ CbCr block $B^{CbCr}$ , chroma subsampling only downsamples $B^{CbCr}$ , but without changing the luma block $B^{Y}$ at all.
