Color Changing Prints on a Metallic Substrate

Printing on a flat metallic substrate has gained popularity in recent years. The reflection of light on a specularly reflecting metallic substrate differs strongly from the reflection of light on a diffusely reflecting medium such as paper. Direct prints o ...

Insight in the 3D morphology of silica-based nanotubes using electron microscopy

Teresa Katharina Dennenwaldt

Amorphous silica-based nanotubes (SBNTs) were synthesized from phosphoryl triamide, OP(NH2)(3), thiophosphoryl triamide, SP(NH2)(3), and silicon tetrachloride, SiCl4, at different temperatures and with varying amount of the starting material SiCl4 using a ...

A Novel Representation of Parts for Accurate 3D Object Detection and Tracking in Monocular Images

Pascal Fua, Vincent Lepetit, Kwang Moo Yi, Alberto Crivellaro, Yannick Verdie, Mahdi Rad

We present a method that estimates in real-time and under challenging conditions the 3D pose of a known object. Our method relies only on grayscale images since depth cameras fail on metallic objects; it can handle poorly textured objects, and cluttered, c ...

Extracting Atrial Activations from Intracardiac Signals during Atrial Fibrillation using Adaptive Mathematical Morphology

Jean-Marc Vesin, Sasan Yazdani, Andréa Buttu, Etienne Pruvot

The detection of intracardiac activities is a major issue in the processing of atrial fibrillation signals. we evaluate a method based on mathematical morphology with an adaptive structuring element in order to extract the atrial activations from intracard ...

Real-time, Automated Characterization of 3D Morphology and Mechanics of Developing Plant Cells

Mahmut Selman Sakar, Dimitrios Felekis, Geraldo Mecja

In this article, we introduce the real-time cellular force microscope (RT-CFM), a high-throughput microrobotic platform for mechanical stimulation and characterization of single cells. We developed computer vision algorithms that fully automate the positio ...

Local Conformational Switching of Supramolecular Networks at the Solid/Liquid Interface

Klaus Kern, Magalí Alejandra Lingenfelder, Fernando Pablo Cometto

We use the electric field in a scanning tunneling microscope to manipulate the transition between open and close packed 2D supramolecular networks of neutral molecules in nonpolar media. We found that while the magnitude of the applied field is not decisiv ...

Color Imaging and Pattern Hiding on a Metallic Substrate

Roger Hersch, Petar Pjanic

We present a new approach for the reproduction of color images on a metallic substrate that look bright and colorful under specular reflection observation conditions and also look good under non-specular reflection observation conditions. We fit amounts of ...

Characterising Internal Heat Transfer in Thermal Protection Systems

Sophia Haussener, Pénélope Leyland, Nikhil Banerji

Thermal protection systems (TPS) are employed for spacecraft to survive high temperature conditions during atmospheric re-entry. For space shuttle type re-entries, the use of ceramic tiles shield the payload from exposure to these high heat fluxes. Recent ...

VOW: Variance-Optimal Wavelets for the Steerable Pyramid

Michaël Unser, Virginie Sophie Uhlmann, Pedram Pad

We study the issue of localization in the context of isotropic wavelet frames. We define a variance-type measure of localization and propose an algorithm based on calculus of variations to minimize this criterion under the constraint of a tight wavelet fra ...
