a.Explain why the linear invariance property of the normalized correlation coefficient, shown in part (a), could be useful for image analysis (< 2 sentences).

b.The range of the NCC is between -1 and 1: -1 <= r <= 1. Explain why this property could be useful for image analysis (< 2 sentences).

c.The expected value of the NCC is 0: E[r]=0. Explain why this property could be useful for image analysis (< 2 sentences).
