In 4:4:4 (a), all components have the same resolution, but chroma components are subsampled in 4:2:2 (b) in a horizontal direction and in 4:2:0 (c) in horizontal and vertical directions.In the codecs, YCbCr 4:2:0 color format is generally used; the resolution of chroma images is a quarter of that of luma before encoding.Lossy compression, meanwhile, generates image degradation when compression rate is high.The existing
