Plot the pixel histogram( take any image) – count of values versus pixel intensity 0 to 255. You must write this from first principles – do not use the MATLAB hist command (although you may use it for comparison and checking your algorithm’s correctness). Plot the cumulative histogram. Do not use the cumsum function in MATLAB (write your own function to achieve this).
