create a symmetry of an image

Is it possible to obtain the bilateral symmetry of an binary image?

An example of the type of result that I search:

x=[true false false;false true false;false true false;false true false;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false true false;false true false;false true false;false true false;false true false;false true false;false true false;true false false];
sym=[0 0 1; 0 1 0; 0 1 0; 0 1 0; 1 0 0;1 0 0;1 0 0;1 0 0;1 0 0;1 0 0;1 0 0;1 0 0;1 0 0;1 0 0; 1 0 0;1 0 0;1 0 0;1 0 0; 0 1 0;0 1 0;0 1 0;0 1 0;0 1 0;0 1 0 ; 0 1 0;0 0 1];

figure, subplot(121), imagesc(x)
subplot(122), imagesc(sym)

Solution

  • As @user2999345 proposes

        % Data set
    x=[true false false;false true false;false true false;false true false;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false false true;false true false;false true false;false true false;false true false;false true false;false true false;false true false;true false false];

    % Flip array about vertical axis
    F=fliplr(x);

    figure
    subplot (121), imagesc(x)
    subplot (122), imagesc(F)
