abstract = "We propose an approach towards measuring the similarity of
restricted deformable objects using three-dimensional point clouds
of them. Basically, given the point clouds of the object in the
ideal and deformed postures, object part labeling is performed
based on RGB to find a first segmentation of the object cloud in
parts. Then two methods are tested for measuring similarity of
each partial clouds set, with verification of their precision and
time: the computation of Mahalanobis distances and of the
Hausdorff distances of the point clouds, the last after
registration and alignment of them. Experimental results show a
faster execution time of the Mahalanobis metric, in despite of its
lower precision in similarity estimation. Several applications in
computer graphics and virtual reality can rely on such result in
order to determine levels of deformation of articulated or
restricted deformable objects.",
