<P>PROBLEM TO BE SOLVED: To provide a method of superimposing digital images of radiograph. <P>SOLUTION: A structure in a first image is mapped onto its corresponding structure in a second image by applying a geometric transformation to the first image so that both images are expressed in a common coordinate system. Starting from initial values, the parameters of the geometric transformation are updated by taking into account the result of an evaluation of a cost function. Finally, the superimposed images may be blended. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
