Sensing reality and communicating bits: A dangerous liaison

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The successful design of sensor network architectures depends crucially on the structure of the sampling, observation, and communication processes. One of the most fundamental questions concerns the sufficiency of discrete approximations in time, space, an ...

An all-in-one solution to geometric and photometric calibration

Pascal Fua, Vincent Lepetit, Julien Pilet, Pascal Lagger, Andreas Geiger

We propose a fully automated approach to calibrating multiple cameras whose fields of view may not all overlap. Our technique only requires waving an arbitrary textured planar pattern in front of the cameras, which is the only manual intervention that is r ...

Tracking and User Interface for Mixed Reality

Touradj Ebrahimi, Yousri Abdeljaoued

This chapter introduces the field of Mixed Reality that merges the real and virtual worlds seamlessly. To develop a Mixed Reality system, two fundamental problems should be addressed: tracking and user interface. Tracking in Mixed Reality is defined as the ...

Robust Feature Point Extraction and Tracking for Augmented Reality

Touradj Ebrahimi

For augmented reality applications, accurate estimation of the camera pose is required. An existing video-based markerless tracking system, developed at the ITS, presents several weaknesses towards this goal. In order to improve the video tracker, several ...

Image-guided Surgical Microscope

Gaëtan Marti

We present an image-guided surgical microscope system using augmented reality image overlays added onto one of the views of the operating microscope. With this system, segmented objects, outlines of risk regions, access pathways or 3D objects, previously e ...

Surgical navigation system

Charles Baur

The invention relates to a surgical navigation system, comprising a microscope to which a 3D measuring apparatus is rigidly fixed, for localising objects within the field of operation. Markers are fixed to the objects the position of which is desirable to ...

Component-based methodology and development framework for virtual and augmented reality systems

Michal Ponder

The very recent revolutionary advancements and wide availability of the real-time 3D graphics technology results in the overwhelming and still quickly growing number of toolkits, game engines, and VR/AR frameworks, which offer very broad collections of fun ...

Fully Automated and Stable Registration for Augmented Reality Applications

Daniel Thalmann, Pascal Fua, Vincent Lepetit

We present a fully automated approach to camera registration for augmented reality systems. It relies on purely passive vision techniques to solve the initialization and real-time tracking problems, given a rough CAD model of parts of the real scene. It do ...

Virtual humans for virtual reality and augmented reality

Daniel Thalmann

The tutorial will explain the techniques for integrating virtual humans into virtual and real environments. It will first present the concept of avatars and autonomous virtual actors and the main techniques to create and animate them (body and face). It wi ...
