Contrast polarity, chromaticity, and stereoscopic depth modulate contextual interactions in vernier acuity

Vernier alignment thresholds are strongly compromised when the vernier is embedded in an array of equal-length flanking lines. Here, we show that these contextual interactions can be diminished by giving the flanks the opposite contrast polarity, e.g., whi ...

How body position changes visual vertical perception after unilateral vestibular loss

Christophe Lopez

Visual vertical perception, posture and equilibrium are impaired in patients with a unilateral vestibular loss. The present study was designed to investigate whether body position (standing upright, sitting on a chair and lying supine) influences the visua ...

Investigating Automatic Dominance Estimation in Groups From Visual Attention and Speaking Activity

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba, Dinesh Babu Jayagopi

We study the automation of the visual dominance ratio (VDR); a classic measure of displayed dominance in social psychology literature, which combines both gaze and speaking activity cues. The VDR is modified to estimate dominance in multi-party group discu ...

A Flexible Technique for Accurate Omnidirectional Camera Calibration and Structure from Motion

Roland Siegwart, Davide Scaramuzza

In this paper, we present a flexible new technique for single-viewpoint omnidirectional camera calibration. The proposed method only re-quires the camera to observe a planar pattern shown at a few different orienta-tions. Either the camera or the planar pa ...

Coevolution of active vision and feature selection

Dario Floreano, Eric Sauser, Toshifumi Kato, Davide Marocco

We show that complex visual tasks, such as position- and size-invariant shape recognition and navigation in the environment, can be tackled with simple architectures generated by a coevolutionary process of active vision and feature selection. Behavioral m ...

A New Approach towards Vision Suggested by Biologically Realistic Neural Microcircuit Models

Henry Markram

We propose an alternative paradigm for processing time-varying visual inputs, in particular for tasks involving temporal and spatial integration, which is inspired by hypotheses about the computational role of cortical microcircuits. Since detailed knowled ...

Multisensor On-the-Fly Localization: Precision and Reliability for Applications

Roland Siegwart, Nicola Tomatis, Björn Jensen, Kai Oliver Arras

In this paper an approach for localization using geometric features from a 360 degree laser range finder and a monocular vision system is presented. Its practicability under conditions of continuous localization during motion in real-time (referred to as o ...

Hybrid, metric - topological, mobile robot navigation

Nicola Tomatis

This thesis presents a recent research on the problem of environmental modeling for both localization and map building for wheel-based, differential driven, fully autonomous and self-contained mobile robots. The robots behave in an indoor office environmen ...

Multisensor On-the-Fly Localization Using Laser and Vision

Roland Siegwart, Nicola Tomatis, Kai Oliver Arras

In this paper a multisensor setup for localization consisting of a 360 degree laser range finder and a monocular vision system is presented. Its practicability under conditions of continuous localization during motion in real-time (referred to as on-the-fl ...

Improving Robustness and Precision in Mobile Robot Localization by Using Laser Range Finding and Monocular Vision

Nicola Tomatis, Kai Oliver Arras

This paper discusses mobile robot localization by means of geometric features from a laser range finder and a CCD camera. The features are line segments from the laser scanner and vertical edges from the camera. Emphasis is put on sensor models with a stro ...
