This thesis deals with 3D shape similarity search. We focus on the main steps of the 3D shape matching process: normalization of 3D models, signature extraction from models, and similarity measure. The first part of the thesis concerns the normalization of 3D models, in particular the search for the optimal pose. We propose a new alignment method of 3D models based on the reflective symmetry and the local translational symmetry. We use the properties of the principal component analysis with respect to the planar reflective symmetry in order to select the eventual optimal alignment axes. The second part of the thesis is dedicated to the shape descriptors and the associated similarity measures. Firstly, we propose a new 3D descriptor, called ...
