A Measure For Spatial Dependency In Natural Stochastic Textures

Sabine Süsstrunk, Roberto Costantini, Gloria Menegaz

Random textures differ from natural textures because they lack structure. Structure is a concept that is difficult to formalize, however, we generally observe that it is associated to spatial dependency between adjacent pixels. Random textures, in fact, ar ...

Point-based computer graphics

Mark Pauly

This course introduces points as a powerful and versatile graphics primitive. Speakers present their latest concepts for the acquisition, representation, modeling, processing, and rendering of point sampled geometry along with applications and research dir ...

Accurate Face Models from Uncalibrated and Ill-Lit Video Sequences

Pascal Fua, Slobodan Ilic, Miodrag Dimitrijevic

In this paper, we propose a face reconstruction technique that produces models that not only look good when texture mapped, but are also metrically accurate. Our method is designed to work with short uncalibrated video or movie sequences, even when the lig ...

Interactive 3D painting on point-sampled objects

Mark Pauly

We present a novel painting system for 3D objects. In order to overcome parameterization problems of existing applications, we propose a unified sample-based approach to represent geometry and appearance of the 3D object as well as the brush surface. The g ...

Wide-baseline Stereo from Multiple Views: a Probabilistic Account

Christoph Strecha

This paper describes a method for dense depth reconstruction from a small set of wide-baseline images. In a widebaseline setting an inherent difficulty which complicates the stereo-correspondence problem is self-occlusion. Also, we have to consider the pos ...

Probabilistic Plane Fitting in 3D and an Application to Robotic Mapping

Roland Siegwart, Jan Weingarten

This paper presents a method for probabilistic plane fitting and an application to robotic 3D mapping. The plane is fitted in an orthogonal least-square sense and the output complies with the conventions of the Symmetries and Perturbation model (SPmodel). ...

Optic-flow-based Navigation for Ultralight Indoor Aircraft

Dario Floreano, Jean-Christophe Zufferey

The goal of this project is to develop an autonomous microflyer capable of navigating within houses or small built environments using vision as main source of information. Flying indoor implies a number of challenges that are not found in outdoor autonomou ...

Spectral Bandwidths for the Detection of Colour within Random Colour Textures

Sabine Süsstrunk, Gianluca Monaci, Gloria Menegaz

We investigated the spectral properties of color detection mechanisms via a noise masking paradigm. Contrast detection thresholds were measured for equiluminant chromatic modulations in the (L-M,S-(L+M))-plane within a random texture. Each texture image wa ...

Spatio-Temporal Shadow Segmentation and Tracking

Touradj Ebrahimi, Elena Salvador

Shadow segmentation is a critical issue for systems aiming at extracting, tracking or recognizing objects in a given scene. Shadows can in fact modify the shape and colour of objects and therefore affect scene analysis and interpretation systems in many ap ...

Towards the Formal Integration of Two Upcoming Standards: IEC61970 and IEC61850

Otto Preiss, Christian Frei, Tatjana Kostic

AbstractThe constant demand for a better integration of utility applications and systems provokes the question on the compatibility of standards that were, and still are, developed for these individual utility disciplines. This paper discusses the need for ...
