(c) The human visual system (HVS) is more sensitive to luminance than chrominance. Chroma subsampling is therefore a tool to compress the video. (i) (ii) Demonstrate the 4:2:0 sampling scheme with a graph and explain how it helps to compress the video. List another THREE (3) subsampling schemes and indicate their compression ratios. Which subsampling scheme is used in H.264 baseline profile?
