MALDONADO, MANUEL A.; SANCHEZ TORRES, GERMAN  e  BRANCH, JOHN WILLIAN. REGISTRATION OF RANGE IMAGES USING A HISTOGRAM BASED METRIC. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.176, pp.27-34. ISSN 0012-7353.

In this paper, a new approach for coarse registration of triangular meshes for three-dimensional object reconstruction is proposed by using the shape-index measure for topological description and the Earth Mover's Distance (EMD) metric for region similarity estimation. Two of its main advantages are independence from initial pre-alignment and spatial transformation, obtaining a more accurate registration regardless of the initial viewing position.
