Quasiconformal Embeddings of Y-Pieces

In this paper we construct quasiconformal embeddings from Y-pieces that contain a short boundary geodesic into degenerate ones. These results are used in a companion paper to study the Jacobian tori of Riemann surfaces that contain small simple closed geod ...

Résistance au déversement des poutres métalliques de pont

Jean-Paul Lebet, Raphaël Thiébaud

Le déversement est un phénomène complexe d’instabilité qui intervient lorsqu’une poutre est sollicitée par un effort de flexion. De nombreuses recherches expérimentales et théoriques, dont les résultats servent de bases aux normes actuelles de la construct ...

Light Transport Matrix recovery for nearly planar objects

Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz, Niranjan Thanikachalam

The light transport matrix has become a powerful tool for scene relighting, owing to the versatility of its representational power of various light transport phenomenon. We argue that scenes with an almost planar surface geometry, even with significant amo ...

State of the Art in Surface Reconstruction from Point Clouds

Andrea Tagliasacchi

The area of surface reconstruction has seen substantial progress in the past two decades. The traditional problem addressed by surface reconstruction is to recover the digital representation of a physical shape that has been scanned, where the scanned data ...

In-Plane Mode Dynamics of Capillary Self-Alignment

Massimo Mastrangeli, Pierre Lambert

We present an experimental study of the complete in-plane dynamics of capillary self-alignment. The two translational (shift) and single rotational (twist) in-plane modes of square millimetric transparent dies bridged to shape-matching receptor sites throu ...

Graph-based Image Inpainting

Michaël Defferrard

The project goal was to explore the applications of spectral graph theory to address the inpainting problem of large missing chunks. We used a non-local patch graph representation of the image and proposed a structure detector which leverages the graph rep ...

Constructing reparameterization invariant metrics on spaces of plane curves

Martins Bruveris, Martin Bauer

Metrics on shape spaces are used to describe deformations that take one shape to another, and to define a distance between shapes. We study a family of metrics on the space of curves, which includes several recently proposed metrics, for which the metrics ...

Weak lensing mass map and peak statistics in Canada-France-Hawaii Telescope Stripe 82 survey

Jean-Paul Richard Kneib, Frédéric Courbin, Georges Meylan, Johan Comparat, Huanyuan Shan

We present a weak lensing mass map covering similar to 124 deg(2) of the Canada-France-Hawaii Telescope Stripe 82 Survey (CS82). We study the statistics of rare peaks in the map, including peak abundance, the peak-peak correlation functions and the tangent ...

2-Point-based Outlier Rejection for Camera-IMU Systems with applications to Micro Aerial Vehicles

Davide Scaramuzza

This paper presents a novel method to perform the outlier rejection task between two different views of a camera rigidly attached to an Inertial Measurement Unit (IMU). Only two feature correspondences and gyroscopic data from IMU measurerments are used to ...

Refining Mitochondria Segmentation in Electron Microscopy Imagery with Active Surfaces

Pascal Fua, Anne Alison Jorstad

We present an active surface-based method for refining the boundary surfaces of mitochondria segmentation data. We exploit the fact that mitochondria have thick dark membranes, so referencing the image data at the inner membrane can help drive a more accur ...
