High‐Gloss SVBRDF Capture Using Bounce Light
Computer Graphics Forum, EarlyView.Abstract Reflectance capture aims at the visual reproduction of an object under varying illumination. Past works differ substantially in their experimental overhead, from single‐ or few‐image approaches, that employ significant (often learned) priors at the expense of biased reconstructions, to more accurate approaches that tend to be time‐consuming ...

Skeletal‐Driven Animation of Anatomical Humans via Neural Deformation Gradients
Computer Graphics Forum, EarlyView.Abstract Most real‐time animation techniques for digital humans are limited to deforming the outer skin surface. Geometric skinning methods are highly efficient but struggle with artifacts such as collapsing joints or self‐intersections when animating inner anatomy along with the outer skin.

Generating functions and short recursions, with applications to the moments of quadratic forms in noncentral normal vectors [PDF]
Using generating functions, the top-order zonal polynomials that occur in much distribution theory under normality can be recursively related to other symmetric functions (power-sum and elementary symmetric functions, Ruben, Hillier, Kan, and Wang ...

Lattice models, cylinder partition functions, and the affine coxeter element [PDF]
, 1998 The partition functions of the affine Pasquier models on the cylinder are calculated in the continuum limit. The partition functions of the models based upon the Â(_n) cycle graphs are first found from the appropriate Coulomb-gas equivalence.

Class polynomials for some affine Hecke algebras
, 2016 Class polynomials attached to affine Hecke algebras were first introduced by He in [13]. They play an important role in the study of affine Deligne-Lusztig varieties. Motivated by [14], we compute the class polynomials attached to an affine Hecke algebra

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities
Computer Graphics Forum, EarlyView.Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Efficient Affine-Invariant Similarity Retrieval
, 2007 We describe novel image similarity measures that are affine-invariant. Based on these new similarity measures, we further describe efficient affine-invariant image indexing algorithms.

On orthogonal polynomials and related discrete integrable systems [PDF]
, 2006 Orthogonal polynomials arise in many areas of mathematics and have been the subject of interest by many mathematicians. In recent years this interest has often arisen from outside the orthogonal polynomial community after their connection with ...

Codimension in planar polynomial differential systems
Electronic Journal of Differential EquationsThe topological classification of large families of polynomial differential systems remains an extremely difficult problem. Even for the simplest nonlinear case, the quadratic systems, this problem is still open.

Establishing Shape Correspondences: A Survey
Computer Graphics Forum, EarlyView.Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...
