HOW TO MOVE THE DIAGONAL ELEMENTS IN MATRIX (ONE PIXELS) FOR IMAGE PROCESSING

HOW TO MOVE THE DIAGONAL ELEMENTS IN MATRIX (ONE PIXELS) FOR IMAGE PROCESSING

[Walter Roberson]

Could you give a small example?

[ajith]

for example

1 2 4
2 5 6
1 3 8

to move the diagonal in one pixel like

8 6 4
3 1 2
1 2 5

and give detail about m*n matrix

Answer 1

[Andrei Bobrov]

I = [1 2 4
2 5 6
1 3 8 ];
ii = 1:size(I,1)+1:numel(I);
I(ii) = I(ii(mod(ii - 2,3)+1));

or

I(eye(size(I))>0) = circshift(diag(I),1);

[ajith]

Thanks a lot sir but i changed the question right now all the elements should change in the diagonal direction for m*n matrix

Answer 2

How about using circshift()?

Answer 3

[Sean de Wolski]

or diag()?

OK, why does your dog have a vest? Just wondering....

[Sean de Wolski]

So she's not a deer during hunting season :)

Ah - I thought she was like a rescue dog, locating and pulling people from rubble after earthquakes.
