Description: matlab coding question digital image processing equalize the original image using histogram equalization he do not use built in functions like histeq i plot s tr for this situation where 0 r 75161

Equalize the original image using Histogram Equalization (HE). Do not use built-in functions like histeq(). i. Plot s = T(r) for this situation, where 0 ≤ r ≤ 255 and 0 ≤ s ≤ 255. ii. Provide the equalized image along with its histogram and cumulative distribution function (cdf).

In MATLAB, define a zero-filled 256x256 matrix named Bars by using the command "zeros". Create 2 vertical bars, centered on the image, of width 3 and height 40, separated from each other by 8 pixels, by setting the appropriate matrix elements to the value 1. Display the image Bars. Your matrix can be displayed as a 2D grayscale image by using the commands "imagesc" and "colormap". Make the image square by using the command "axis square". Pick a horizontal line through the center of the test pattern. Plot the intensity profile of this line. Label the x and y axes appropriately. To accurately reconstruct this image by sampling—ignoring edge effects—how often (for every how many pixels) must you sample (hint: ∆x = 3 pixels)? What is the fundamental principle behind sampling?
