Perhaps something like (untested):

diffImage = A ~= B; % Find pixels that are not the same.
[rows, columns] = find(diffImage); % Find their rows and columns.
plot(columns, rows, 'ro'); % Plot circle over those pixels that are not the same.

it makes a strange thing , it copy the shape three time and plot it . and rotate the result 180 degree

Alright. Tell me exactly how I can help you.

i don't want to appear the shape three times i just need one shape in figure

ibrahim, I guess my gentle hint was not taken. You were supposed to say to yourself, "He's right. I haven't given him anything whatsoever that he can help me with. I have not given him 1.png or 2.png. I have not even given him my code so he can reproduce my 3 red plots. How can he do anything at all for me? There's no way he can do anything to help me. I guess I'd better attach my image files and my m-file so he'll have something to work with."

age = A ~= B; % Find pixels that are not the same. [rows, columns] = find(diffImage); % Find their rows and columns. plot(columns, rows, 'ro'); % Plot circle over those pixels that are not the same...
