MATHICSE Technical Report: THU-Splines - Highly Localized Refinement on Smooth Unstructured Splines

We present a novel method named truncated hierarchical unstructured splines (THU-splines) that supports both local h-refinement and unstructured quadrilateral meshes. In a THU-spline construction, an unstructured quadrilateral mesh is taken as the input co ...

DeepSVG: A Hierarchical Generative Network for Vector Graphics Animation

Alexandre Massoud Alahi, Radu Timofte

Scalable Vector Graphics (SVG) are ubiquitous in modern 2D interfaces due to their ability to scale to different resolutions. However, despite the success of deep learning-based models applied to rasterized images, the problem of vector graphics representa ...

CS2 Reductive Coupling to Acetylenedithiolate by a Dinuclear Ytterbium(II) Complex

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez, Davide Toniolo

The activation of CS2 is of interest in a broad range of fields and more particularly in the context of creating new C‐C bonds. The reaction of the dinuclear ytterbium(II) complex [Yb2L4], 1, (L = (OtBu)3SiO‐) with carbon disulphide led to the isolation of ...

An isogeometric boundary element method for electromagnetic scattering with compatible B-spline discretizations

Rafael Vazquez Hernandez

We outline the construction of compatible B-splines on 3D surfaces that satisfy the continuity requirements for electromagnetic scattering analysis with the boundary element method (method of moments). Our approach makes use of Non-Uniform Rational B-splin ...

Compressed imaging by sparse random convolution

Theo Lasser, Aurélien Bourquard, Antonio Lopez

The theory of compressed sensing (CS) shows that signals can be acquired at sub-Nyquist rates if they are sufficiently sparse or compressible. Since many images bear this property, several acquisition models have been proposed for optical CS. An interestin ...

Stream Carving: an Adaptive Seam Carving Algorithm

Pierre Vandergheynst, Alexandre Massoud Alahi, Daniel Domingues

We propose a new content-aware image resizing scheme, "Stream Carving", which is based on the well-known seam carving method. Our algorithm may introduce larger seams in the retargeted image, i.e. seams with a width larger than one pixel, that we call "str ...

Towards Geoservices Portals MEDIAMAPS: WGIS trends for business applications

Stéphane Joost

The developments within the MEDIAMAPS project were motivated by, the idea to provide small and medium companies with a solution to benefit from Web Business Geographic Applications (TYBGA) advantages at an affordable price : a Webmapping application servic ...

Perceptually tuned generation of grayscale fonts

Roger Hersch

A new approach to grayscale font generation improves on the fuzzy characters produced by existing methods by incorporating the expertise of type designers into rules for character-outline weight and phase control. The method we propose for synthesizing hig ...

Advanced grid constraints: performances and limitations

Roger Hersch

Existing font rasterization systems use grid constraints or hints in order to rasterize outline characters. Advanced grid constraints include snapping techniques for producing uniform raster characters without preliminary outline regularization. They also ...
