Please help me with exercise 2, I urgently need help on image processing

MATLAB

Woman_darkhair

512x512 uint8

Exercise 1:

Load the image rose1024.tif by using the following commands:

>> f=imread('rose1024','tif'); %

>> whos %

Name Size Bytes Class

f 1024x1024 1048576 uint8 array

Grand total is 1048576 elements using 1048576 bytes

>> imagesc(f);colormap(gray) %

Enter a describing comment after each % symbol in the lines of code above.

This is a 1024 1024 intensity image of class uint8.

Now flip the image vertically using the statement

fp = f (end :-1 : 1, :);

Then obtain a section out of the original image, using the command

fc = f(257:768, 257:768);

We call this a cropped image.

Next, obtain a sub-sampled (decimated) image using the statement

fs = f(1:2:end, 1:2:end);

Finally, obtain a horizontal scan line through the middle of the original image, using the command

plot(f(512, :)).

Exercise 2:

Repeat the procedure of Exercise 1 using the 512 512 image woman_darkhair.tif.
