Dithering or also known as half-tone printing is often used when converting grayscale images to monochrome. There are several different types of dithering. By using the 17 3 9V pattern mask given as (5 1 2 and by referring to Figure Q2() that shows a 8 4 6 small portion of the pixel data for a grayscale image. briefly explain the pattern dithering process and compute the output pixels value after pattern dithering is applied to the image. Also suggest other types of general dithering that can be applied to the image [11 marks] 75 42 40 84 150 171 136 75 41 138 155 118 67 73 1 0 1 0 1 0 0 1 99 106 80 52 46 45 255 255 255 255 255 255 255 0 119 138 200 62 32 30 255 37 40 33 33 255 0 40 46 30 31 255 1 255 29 255 1 33 255 0 1 0 Figure (20) Dithering or also known as half-tone printing is often used when converting grayscale images to monochrome.
