| contents | Medida de similitud para objetos 2D y 3D a través de una energía de transformación óptima Hermilo Sánchez Cruz Ernesto Bribiesca Correa Computación A method of transforming an object O1 into another object O2 is presented in this work. The computation ofthis transformation is performed to measure shape similarity of objects. The considered objects arecomposed of spels (voxels for 3D objects and pixels for 2D objects). The difference in the shape of objects isperformed by computing the number of spels to be moved, and by the distance they have to cover intransforming one object into another.This work is based on a method of transformation of objects, presented by Bribiesca [1](1996). Thecontribution of this work is to optimise the Bribiesca´s method by using principal axes to orientate objects,and by computing minimum energy or distance, to go from an object into another. To show the mostimportant properties of our method, a set of 2D objects are analysed, and finally, this method is applied to 3Dreal world-objects, like those of some cars and some volcanoes near to the basin of Mexico. 2003 artículo científico 1405-5546 https://www.redalyc.org/articulo.oa?id=61570107 en http://www.redalyc.org/revista.oa?id=615 Computación y Sistemas application/pdf Instituto Politécnico Nacional Computación y Sistemas (México) Num.1 Vol.7 |
