Volumetric shape contexts for mesh co-segmentation

In the field of mesh segmentation, co-segmentation techniques achieve state-of-the-art performance; however, the segmentation results rely on the shape descriptors used in the segmentation process. In this paper, we propose a novel type of descriptor called the “volumetric shape context” (VSC). For each triangle in the mesh, the VSC describes the distribution of the shape’s volume relative to t...

Anisotropic geodesics for live-wire mesh segmentation

We present an interactive method for mesh segmentation that is inspired by the classical live-wire interaction for image segmentation. The core contribution of the work is the definition and computation of wires on surfaces that are likely to lie at segment boundaries. We define wires as geodesics in a new tensor-based anisotropic metric, which improves upon previous metrics in stability and fe...

3D Wire mesh photonic crystals.

We have investigated the electromagnetic properties of a 3D wire mesh in a geometry resembling covalently bonded diamond. The frequency and wave vector dispersion show forbidden bands at those frequencies n0, corresponding to the lattice spacing, just as dielectric photonic crystals do. But they have a new forbidden band which commences at zero frequency and extends, in our geometry, to , 12 n0...

Optimization of high temperature SiC volumetric solar absorber

Focusing on radiative properties (absorption and scattering coefficient, scattering phase-function) of silicon carbide foams, several predictive models are compared to spectral transmittance and reflectance measurements (bi-directional and directionalhemispherical) in the aim of determining new correlations based on ceramic foam characteristics (struts/pores size and porosity). A mono-dimension...
