Optimized scattering compensation for time-of-flight camera

Heinz Hügli

Recent time-of-flight (TOF) cameras allow for real-time acquisition of range maps with good performance. However, the accuracy of the measured range map may be limited by secondary light reflections. Specifically, the range measurement is affected by scatt ...

Pedestrian detection by range imaging

Heinz Hügli

Remote detection by camera offers a versatile means for recording people activities. Relying principally on changes in video images, the method tends to fail in presence of shadows and illumination changes. This paper explores a possible remedy to these pr ...

Geometry-based scene representation with distributed vision sensors.

Pascal Frossard, Ivana Tosic

This paper addresses the problem of efficient representation and compression of scenes captured by distributed vision sensors. We propose a novel geometrical model to describe the correlation between different views of a three-dimensional scene. We first a ...

Probabilistic Head Pose Tracking Evaluation in Single and Multiple Camera Setups

Jean-Marc Odobez, Silèye Oumar Ba

This paper presents our participation in the CLEAR 07 evaluation workshop head pose estimation tasks where two head pose estimation tasks were to be addressed. The first task estimates head poses with respect to (w.r.t.) a single camera capturing people se ...

Automated Digital Image Processing for Volume Change Measurement in Triaxial Cells

Lyesse Laloui, Laurent Vulliet

An automated digital image processing technique is presented for the measurement of specimen volume change during triaxial testing. A digital camera is fixed at a constant distance from the triaxial cell. Pictures taken at various intervals are processed ( ...

Autonomous multisensor tracking surveillance system

Remo Heimgartner

In the world of video especially in video processing important steps are being taken at this time. Research projects around the world are tackling all kind of tracking problems and segmentation of video images. Others are doing feature extraction, image en ...

Automatic Red-Eye Removal based on Sclera and Skin Tone Detection

Patrick Vandewalle, Flavien Volken, Johann Terrier

It is well-known that taking portrait photographs with a built in camera may create a red-eye effect. This effect is caused by the light entering the subject’s eye through the pupil and reflecting from the retina back to the sensor. These red eyes are prob ...

Human body pose detection using Bayesian spatio-temporal templates

Pascal Fua, Vincent Lepetit, Miodrag Dimitrijevic

We present a template-based approach to detecting human silhouettes in a specific walking pose. Our templates consist of short sequences of 2D silhouettes obtained from motion capture data. This lets us incorporate motion information into them and helps di ...

Virtual Sensor Design

Sabine Süsstrunk, Roberto Costantini

We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...
