MeshUDF: Fast and Differentiable Meshing of Unsigned Distance Field Networks

Pascal Fua, Benoît Alain René Guillard, Federico Stella

Unsigned Distance Fields (UDFs) can be used to represent non-watertight surfaces. However, current approaches to converting them into explicit meshes tend to either be expensive or to degrade the accuracy. Here, we extend the marching cube algorithm to han ...

The CT-cube: A framework for the design and the assessment of computational thinking activities

Francesco Mondada, Alberto Piatti, Laila Abdelsalam El-Hamamsy

Computational thinking is a fundamental competence that is being introduced in K-12 and succeeding curricula worldwide. Despite this huge effort, many computational thinking models in the literature do not explicitly take into consideration the pupils’ age ...

Human Detection and Segmentation via Multi-view Consensus

Pascal Fua, Mathieu Salzmann, Isinsu Katircioglu, Helge Jochen Rhodin

Self-supervised detection and segmentation of foreground objects aims for accuracy without annotated training data. However, existing approaches predominantly rely on restrictive assumptions on appearance and motion. For scenes with dynamic activities and ...

Retrospective correction of involuntary microscopic head movement using highly accelerated fat image navigators (3D FatNavs) at 7T

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Daniel Gallichan

PURPOSE: The goal of the present study was to use a three-dimensional (3D) gradient echo volume in combination with a fat-selective excitation as a 3D motion navigator (3D FatNav) for retrospective correction of microscopic head motion during high-resoluti ...

Method and apparatus for 3d object shape and surface topology measurements by contour depth extraction acquired in a single shot

Christian Depeursinge, Daniel Boss, Yves Delacrétaz

The invention relates to a method and apparatus for topological or shape measurement of objects of any size, by using an interferometric technique comprising an optical source, with selectable coherence, allowing contouring from single shot interferograms ...

Precision Isosurface Rendering of 3-D Image Data

Michaël Unser, Philippe Thévenaz

We address the task of rendering by ray tracing the isosurface of a high-quality continuous model of volumetric discrete and regular data. Based on first principles, we identify the quadratic B-spline as the best model for our purpose. The nonnegativity of ...

High-Quality Isosurface Rendering with Exact Gradient

Michaël Unser, Philippe Thévenaz

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 a sum of nonnegative B-splines, we are able to confine the potential locatio ...
