Abstract
Images representing one and the same scene, but acquired under conditions such taht the subject has moved, are automatically reset by making an automatic selection of a homogenous population of landmarks and by computing the shift vectors associated with these landmarks. It is shown that, in order to select the landmarks, it is worthwhile to characterize the image by a certain number of characteristic mangitudes representing the solidity of these landmarks. The solidity of the landmarks is the ability of a landmark to be the site of an exact measurement of shift for a required precision.
