Partial difference equations on graphs for Mathematical Morphology operators over images and manifolds
The main tools of Mathematical Morphology are a broad class of nonlinear image operators. They can be defined in terms of algebraic set operators or as Partial Differential Equati...

High-quality isosurface rendering with exact gradient
We address the task of rendering by ray tracing the isosurface of a high-quality continuous spline model of volumetric discrete and regular data. By expressing the spline model as...
