This is a job for imregister.

can you provide me with some example how to implement it in my question ? Thank You

Should I assume you are able to write the code for importing the images already? It would be more efficient, if you post the current code you have tried and ask a specific question.

img1 = imread('image1.tiff');
img2 = imread('image2.tiff');
% moving_reg = imregister(moving,fixed,transformType,optimizer,metric)
optimizer = registration.optimizer.RegularStepGradientDescent;
metric    = registration.metric.MeanSquares;
[img1X, reg] = imregister(img1, img2, 'rigid', optimizer, metric)

Does this work? I cannot test it, because I do not have the Image Processing Toolbox. All I've done to create this example was to read the documentation. Try this by your own also: doc imregister (link) .
