This paper deals with the following growth model; let \(\{K_t\}\), \(t\geq t_0\), be a growing family of connecting sets, where \(K_{t_0}\) is the initial configuration, and \(K_s\subset K_t\) for \(s< t\). The growth is localized at a finite number of points \(a_j(t)\), \(1\leq j\leq d\), so that \(K_t\setminus K_{t_0}\) consists of \(d\) disjoint ...

We have seen in the previous chapters how an elliptic operator can be associated in a natural way with a geometric Riemannian structure. In a similar way sub-elliptic operators arise from similar structures, called sub-Riemannian structures, which will be discussed next. References for sub-Riemannian manifolds are [27] and [92].

Surface editing operations commonly require geometric details of the surface to be preserved as much as possible. We argue that geometric detail is an intrinsic property of a surface and that, consequently, surface editing is best performed by operating over an intrinsic surface representation.

Indexing through laplacian spectra
Computer Vision and Image Understanding, 2008With ever growing databases containing multimedia data, indexing has become a necessity to avoid a linear search. We propose a novel technique for indexing multimedia databases in which entries can be represented as graph structures. In our method, the topological structure of a graph as well as that of its subgraphs are represented as vectors whose ...

Laplacian Sparse Coding, Hypergraph Laplacian Sparse Coding, and Applications
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2013Sparse coding exhibits good performance in many computer vision applications. However, due to the overcomplete codebook and the independent coding process, the locality and the similarity among the instances to be encoded are lost. To preserve such locality and similarity information, we propose a Laplacian sparse coding (LSc) framework.
