Step 1: Plot the original Histogram

Step 2 : Perform Histogram Equalization

Step 3: Make new histogram 1 table

Step 4: Plot the equalized Histogram 1

Intensity (r)	0	1	2	3
No. of pixels $(nk)$	0	0	70	30

Step 5 : Again Perform Histogram Equalization on Histrogram 1

Step 6: Plot the equalized Histogram 2

Intensity (r)	0	1	2	3
No. of pixels $(n_k)$	0	0	70	30

As we can see equalizing the histogram twice will gives the same histogram.
