TASK III. In this task you will apply the commands from Task I to matrices representing

images. Recall that a black and white digital image can be represented by a matrix whose

entries $($pixels$)$ correspond to the intensities $($gray levels$)$ of the image at different points.

$($a$)$ Download bridge.jpg to the folder TaskIII.

$($b$)$ Read the image into your MATLAB session by naming A the matrix representing it$.$

Display the image.

$($c$)$ Determine the size of the matrix A$.$

Apply to the matrix A an appropriate command from Task I to obtain the following

images:

$($d$)$ Original image upside down. Call its matrix A$2.$ Save the new image and the matrix A$2$

under the names bridge$2.$jpg and A$2.$mat, respectively, in the folder TaskIII.

$($e$)$ Reflection of the original image with respect to its middle vertical axis. Call its matrix

A$3.$ Save the new image and the matrix A$3$ under the names bridge$3.$jpg and A$3.$mat,

respectively, in the folder TaskIII.

$($f$)$ Upper right subimage of the original image of size $200\backslash$times $200.$ Call its matrix A$4.$ Save the

new image and the matrix A$4$ under the names bridge$4.$jpg and A$4.$mat, respectively,

in the folder TaskIII.

$($g$)$ The image represented by the matrix obtained from A by deleting the even rows. Call

the new matrix A$5.$ Save the new image and the matrix A$5$ under the names bridge$5.$jpg

and A$5.$mat, respectively, in the folder TaskIII.

$($h$)$ The image represented by the transpose of A$.$ Call the new matrix A$6.$ Save the new

image and the matrix A$6$ under the names bridge$6.$jpg and A$6.$mat, respectively, in the

folder TaskIII.

$($i$)$ Save the original image and the images obtained in items $($d$)$ through $($h$).$ Write next to

each image its name and the command that you used to obtain the matrices A$2,$ A$3,$ A$4,$

A$5,$ A$6,$ respectively. Save all the images in the order bridge.jpg$,$ bridge$2.$jpg$,,$

bridge$6.$jpg
