Hi, I am experimenting image registration in Matlab. How can I register an image with a flipped versions of this image? any suggestion? Here is an example:

    clc ; clear; close all;
    fixed = imread('cameraman.tif');
    moved = flip(fixed,2);
    figure, imshowpair(fixed, moved, 'montage')
            title( 'Un-registred');
   [optimizer,metric] = imregconfig('monomodal')
   optimizer.MaximumIterations = 600;
   registered = imregister(moved, fixed, 'affine', optimizer, metric);
   figure, imshowpair(fixed, registered, 'montage')
   title( 'registred');

I also tried these codes but nothing work:

 tformSimilarity = imregtform(moved,fixed,'similarity',optimizer,metric);
 registered  = imregister(moved,fixed,'affine',optimizer,metric,...
       'InitialTransformation',tformSimilarity);  
 figure, imshowpair(fixed, registered, 'montage')
         title( 'registred'); 
 % another try
  tformEstimate = imregcorr(moved,fixed);
  Rfixed = imref2d(size(fixed));
  registered = imwarp(moved,tformEstimate,'OutputView',Rfixed);
  figure, imshowpair(fixed, registered, 'montage')
         title( 'registred');
