Question 4 needed

3. Histogram of a 3 bit image is thown in the following, iablen [25] 4. (a) The two images shown below in Figure 3 are quite different, hut their listogratis ate identical. Both images have size 88. with black and white pixels Suppose that both images are blurred with a 33 smoothing mask. Would the resultant histograms still be the same? Draw spproximately the two histograms and explain your answu [16] Figure 3: Two images with same listogram. (Questron 4ia) (Note the dark lines that appear amound the two images arr usert to signify the houndaries of the images but are not pail of theul. (b) Compare between mean and median filters. [9] 5. Histogram of a 3 bits/pixel square image is given in Figure 4 (a). (a) Find out the size of image and total mumbet of phacts [5] (b) What would be new histogram if we muke MSJ (Mext kignifiemm bit) equal to 1 . (c) Specified normalized histogran (prid) is a1ven in Figure 1(b). Lee histugran specification to generate histogram of enlanced imngy Show I lw limal Iistogrimi. [15] 6. The diagram in Figure 5 contains several curves that could be used to trausform ilre brightness values of a monochrome image by the operation s=I(r) where r is the input intensities nnd s is the output intensity. Shown in Figure 6 are four pairs of histograns. Identify the transforunation curse best associated with each pair and write the letter in the space in the center column and explain your
