<I>> What I want is to determine the coordinates of these "target" points, based on the transformation determined by the corresponding "known" points.</I><P>
could you please elaborate? Do you know the corresponding point pairs (known_i,target_i)?<P>
There are many "transformations", I remember seeing a projection model based on a 4x4 matrix in uni.<P>
Determining the entries would mean to solve the resulting linear equations.<P>
Again it depends on the class of allowed transformations.<P>
