Suppose you have an 8 x 8 block of pixels that you are going to compress using the JPEG method. The block is currently represented as 24-bit RGB color, with cight bits per color component. Calculate the number of bytes necessary to store this image data in the RGB model and in the YUV model with 4:2:0 chrominance downsampling. Then calculate the compression rate. [4 marks] Draw the dithered image based on the pixel given by Figure Q5(e) with the pattern mask given as follow: B 11 0 0 0 0 0 0 0 0 255 155 255 155 255 155 255 155 255 155 255 155 255 155 255 155 155 255 255 200 255 155 255 255 200 255 155 255 255 200 255 155 255 255 200 255 155 255 255 200 255 155 255 255 200 255 155 255 255 200 255 155 255 255 200 255 Figure Q5(e) [6 marks] Suppose you have an 8 x 8 block of pixels that you are going to compress using the JPEG method.
