We consider linear transformations between the object fragments and present the method through 2D and 3D affine transformations. The basic idea is to construct and solve a polynomial system of equations which provides the unknown parameters of the alignment. We have quantitatively evaluated the proposed algorithm on a large synthetic dataset containing 2D and 3D images. The results show that the method performs well and robust against segmentation errors. We also present experiments on 2D real images as well as on volumetric medical images applied to surgical planning. © 2010 Springer-Verlag.</p>1 aDomokos, Csaba1 aKato, Zoltan1 aDaniilidis, Kostas1 aMaragos, Petros1 aParagios, Nikos  uhttps://tisat.inf.u-szeged.hu/publication/affine-puzzle-realigning-deformed-object-fragments-without-correspondences
