Exercise $3\mathrm{.}1$ Using the examples presented on arithmetic operations $($Examples $3\mathrm{.}13\mathrm{.}4)$

we can investigate the use of these operators in a variety of ways. First, load the Matlab

example images $$rice$.$png$$ and $$cameraman$.$tif$.$ Investigate the combined use of the Matlab

imresize$()$ and size$()$ functions to resize one of the images to be the same size as the other.

The Matlab command whos used in the syntax $$whos v$$ will display information about the

size and type of a given image or other variable v$.$

Try adding both of these images together using the standard Matlab addition operator

$$ and displaying the result. What happens? Now add them together by using the imadd$()$

function but adding a third parameter to the function of $$uint$16$ or $$double$$ with quotes

that forces an output in a $16-$bit or floating$-$point double$-$precision data type. You will need

to display the output using the imagesc$()$ function. How do these two addition operator

results differ and why do they differ?

Repeat this exercise using the standard Matlab subtraction operator $$ and also by

using the imsubtract$()$ function.
