Grouping explains contextual modulation in low level vision

Michael Herzog, Bilge Sayim

Performance on a target can be modified by contextual elements. For example, when a Vernier is flanked by two lines, offset discrimination deteriorates compared to an unflanked presentation. This contextual modulation is usually explained by local spatial ...

Vision-aided inertial navigation system for robotic mobile mapping

Jan Skaloud, Fadi Atef Bayoud

A mapping system by vision-aided inertial navigation was developed for areas where GNSS signals are unreachable. In this framework, a methodology on the integration of vision and inertial sensors is presented, analysed and tested. The system employs the me ...

Blue laser diodes including lattice-matched Al0.83In0.17N bottom cladding layer

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Julien Dorsaz, Antonino Francesco Castiglia, Gatien Cosendey

A report is presented on InGaN/GaN multiple quantum well laser diodes, grown by metal organic vapour phase epitaxy on c-plane sapphire substrates, including an Al0.83In0.17N cladding layer lattice-matched to GaN. Lasing action is demonstrated for gain-guid ...

Visible InGaN/GaN quantum-dot materials and devices

Nicolas Grandjean, Marc Ilegems

General properties of III-V nitride-based quantum dots (QDs) are presented, with a special emphasis on InGaN/GaN QDs for visible optoelectronic devices. Stranski-Krastanov GaN/AIN dots are first discussed as a prototypical system. it is shown that the opti ...

Cellular photoperception and photoactive proteins

Majed Chergui, Stefan Haacke

A review. The crucial steps of cellular photoperception are characterized and followed in real time by laser spectroscopy down to a few tens of femtoseconds. The photoactive proteins studied here are involved in major natural processes such as vision (bact ...

A three-degree-of-freedom anthropomorphic oculomotor simulator

Jamie Paik

For a sophisticated humanoid that explores and learns its environment and interacts with humans, anthropomorphic physical behavior is much desired. The human vision system orients each eye with three-degree-of-freedom (3-DOF) in the directions of horizonta ...

Embedded 3D vision system for automated micro-assembly

Heinz Hügli

Machine vision plays an important role in automated assembly. However, present vision systems are not adequate for robot control in an assembly environment where individual components have sizes in the range of 1 to 100 micrometers, since current systems d ...

Elements for European logistics policy - A discussion paper

Tristan Chevroulet

Following a Finnish initiative the European Commission is preparing a communication on logistics in 2006. To support the preparations Finland arranged the so called EULOC-process in which logistics experts from different countries were invited to participa ...

Automatic Self-Calibration of a Vision System during Robot Motion

Roland Siegwart, Davide Scaramuzza

This paper presents a new technique to estimate the extrinsic parameters of a robot-vision sensor system. More in general, this technique can be adopted to calibrate any robot bearing sensor. It is based on the Extended Kalman Filter. It is very simple and ...
