In many applications, e. g. object recognition, decomposition of a shape is of great interest. We present a decomposition algorithm for 3D shape that is based on a multiresolution structure. The shape is hierarchically decomposed according to local thickness. A merging process is introduced for merging of small components to more significant parts. As a side effect of the algorithm, we also obtain a way of smoothing noisy shapes.
