(a) Suppose the distorted image coordinates and its original image coordinates can be related by affine transformation. What is the minimum number of corresponding pixel pairs that must be determined using least square method? Briefly explain your answer. 9 11 0 0 0 12 Pixel C 12 12 120 125 20 8 11 0 120 120 11 0 122 11 110 0 0 0 130 130 135 0 0 0 140 0 0 80 12 Figure 2(a) Pixel C is at the center of the surrounding pixels and is at equal distance to each of the 4 pixels as shown in Figure 2(a). Determine all the possible intensity values of Pixel C using (1) nearest neighbour interpolation and (ii) bilinear interpolation?
