clc;

clear all;

close all;

% read the image

I = imread('pout.tif');

J = imread('football.jpg');

% Adjust the contrast level

K = imadjust(I);

L= imadjust(I,[0.3 0.7],[]); % specifing the contrast limit

M= imadjust(I,[0.7 0.8],[]); % specifing the contrast limit

N= imadjust(I,[0.1 0.4],[]); % specifing the contrast limit

% Adjust the contrast level of colur image

O = imadjust(J,[.2 .4 0; .3 .5 0.1],[]);

P= imadjust(J,[.2 .3 0; .4 .7 1],[]); % specifing the contrast limit

Q= imadjust(J,[.1 .4 0; .5 .6 .8],[]); % specifing the contrast limit

R= imadjust(J,[.2 .3 0; .5 .7 1],[]); % specifing the contrast limit

% show the resultant image

Please add comments and documentation so that people can understand how this code is an implementation of a pacemaker.
