Canonical fitting of deformable part models

I describe a system that fits deformable models to range data. Models are represented by using modal dynamics applied to volumetric primitives, which significantly improves the computational complexity of both model recovery and subsequent processing. Given a segmentation of the range data into parts (see reference [16]), a volumetric description is obtained by a fitting procedure that minimizes squared error between the range measurements and the model's visible surface. For simple part shapes it is possible to compute the deformable model's parameters using only the shape of its symmetry axes.
