how can i translate a 2D image in x ,y directions using matlab?

hi all

i have a 2D image , how can i translated it in x direction by using

from :x-translation=-tx;to:x-translation=tx;step=5;

and in y direction

from :y-translation=-ty;to:y-translation=ty;step=5;

also , how can i select suitable values for tx and ty?

Did you click the link? You have to download it and save it somewhere on your MATLAB path from the URL in my above answer.

thankssssss.

i download your file and i will read it and try to implement it ony my images.can i ask you if i have any question in the code?

[mmm ssss]

for example

elseif dims == 2

T_dims = [1 2]; %Dimensions in order

A = zeros(3);

A([1 5 9]) = 1;

A(3,1:2) = translation;

can you illustrate this to me?why you create A?

also about

translation =

[row_shift col_shift] for 2D images

how this can be modified according to my case?

from :x-translation=-tx;to:x-translation=tx;step=5;

and in y direction

from :y-translation=-ty;to:y-translation=ty;step=5;

i am new to matlab ,so please be simple in your reply.

regards

You don't need to modify anything, read the help - it explains how to use the inputs to translate the way you want.

A is the transformation matrix.
