  abstract =	 {We consider the problem of planar object
                  registration on binary images where the aligning
                  transformation is restricted to the group of {\em
                  affine} transformations. Previous approaches usually
                  require established correspondences or the solution
                  of nonlinear optimization problems. Herein we show
                  that it is possible to formulate the problem as the
                  solution of a system of up to third order polynomial
                  equations. These equations are constructed in a
                  simple way using some basic geometric information of
                  {\em binary} images. It does not need established
                  correspondences nor the solution of complex
                  optimization problems. The resulting algorithm is
                  fast and provides a direct solution regardless of
                  the magnitude of transformation.},
