d. The two sub-images in figure2 shown were extracted from the top right corners of figures1 (c) and (d), respectively. Thus, the sub-image on the lef is the result using a geometric mean filter of the same size the i. Explain why the sub-image obtained with geometric mean filtering is less blurred. (Hint: Start your analysis by examining a 1-D step transition in intensity). [5 points] Ancuran. ii. Explain why the black components in the right image are thicker. [5 points]
