1. A method of mapping geometric objects in a digital target comprising the steps of: selecting at least one anchor object part of a model image comprising at least one geometric object; displaying said target image; mapping said anchor object into said target image so as to obtain a mapped anchor object by manually indicating a corresponding anchor object in said target image; computing a geometric transformation on the basis of at least one correspondence between an anchor object and a corresponding mapped anchor object; and automatically mapping the geometric object from said model image to a corresponding mapped position in said target image by applying the calculated geometric transformation to said geometric object in said model image, encoded with respect to said anchor objects.
