A method for processing a plurality of input images containing variable content
that is filled into respective, fixed templates. The method includes comparing
the images to collect a group of the images having a high degree of similarity
therebetween, and combining the images in the group so as to distinguish the variable
content from a fixed portion common to a preponderant number of the images in the
group. The fixed portion is processed to reconstruct the fixed template that is
common to at least some of the images among the preponderant number, and information
is extracted from the images using the reconstructed template.
