Mesh alignment using grid based PCA.

Kaye, David and Ivrissimtzis, Ioannis (2015) 'Mesh alignment using grid based PCA.', in Proceedings of the 10th International Conference on Computer Graphics Theory and Applications (VISIGRAPP 2015) : Berlin, Germany, 11-14 March 2015. , pp. 174-181.


We present an algorithm for mesh alignment by performing Principal Components Analysis (PCA) on a set of nodes of a regular 3D grid. The use of a 3D lattice external to both inputs increases the robustness of PCA, particularly when dealing with meshes of different and possibly uneven vertex density. The proposed algorithm was tested on meshes that have undergone standard mesh processing operations such as smoothing, simplification and remeshing. In several cases the results indicate an improved robustness compared to performing PCA directly on mesh vertices.
