                         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
