Answer #1

The first image represents the histogram equalization

The columns represent possible intensity level(rk), Number of pixels of particular intensity level(rk), rk/MN, rk/MN, and P(rk) and rounded off values respectively

Since it is a 3-bit image k=8(0 to 7)

8x6 image 9x oun de o 32 5035 D 2 25 5 35 75 3 2 64 itog yamThe rounded off values represent the equalized intensity values.

For histogram specification

STI) ON 2 To ohtain hito 9(3)

we calculate all possible intensity transformations for the expected output values for z.

The histogram specification is as follows:

2 0 015625 03123o |牛 |e.0.3/251 0,0625 4 05 125 0 6 32 3 L

We observe that the obtained histograms are same for both the techniques.
