( Dithering or also known as half-tone printing is often used when converting grayscale images to monochrome. Describe THREE (3) types of dithering algorithms. [3 marks] Figure Q3(c) shows a small portion of the pixel data for a grayscale image. 8 3 4 By using the pattern mask given as 6 1 2, briefly explain the dithering 7 5 9 process and compute the output pixels value after dithering. 0 255 99 42 75 119 150 138 0 0 255 106 40 84 138 171 155 0 255 80 41 73 111 136 118 0 255 52 40 46 62 75 67 0 255 46 33 30 32 37 40 0 255 45 33 31 30 29 33 0 255 255 255 255 255 255 255 0 0 0 0 0 0 0 0 Figure Q3(0)
