Curvature-based regularization for surface approximation
We propose an energy-based framework for approximating surfaces from a cloud of point measurements corrupted by noise and outliers. Our energy assigns a tangent plane to each (noi...

An Efficient Algorithm for the Genus Problem with Explicit Construction of Forbidden Subgraphs
act We give an algorithm for imbedding a graph G of n vertices onto an oriented surface of minimal genus g. If g > 0 then we also construct a forbidden subgraph of G which is ho...

3D image and graph based Computation of Protein Surface
The accessible surface of a macromolecule is a significant determinant of its action. The interaction between biomolecules or protein-ligand is dependent on their surfaces rather ...

Algorithmic Graph Minor Theory: Decomposition, Approximation, and Coloring
At the core of the seminal Graph Minor Theory of Robertson and Seymour is a powerful structural theorem capturing the structure of graphs excluding a fixed minor. This result is ...

Minimum Ratio Contours on Surface Meshes
We present a novel approach for discretely optimizing contours on the surface of a triangle mesh. This is achieved through the use of a minimum ratio cycle (MRC) algorithm, where ...
