Dictionary learning in stereo imaging

This paper presents a new method for learning overcomplete dictionaries adapted to efficient joint representation of stereo images. We first formulate a sparse stereo image model where the multi-view correlation is described by local geometric transforms o ...

Hardware Implementation of an Omnidirectional Camera with Real-time 3D Imaging Capability

Pierre Vandergheynst, Alexandre Schmid, Luigi Bagnato, Yusuf Leblebici, Laurent Jacques, Hossein Afshari

A new plenoptic sensor inspired from the visual system of flying insects is introduced. This sensor is referred to as the Panoptic camera. This system has two distinguished features. First it is an omnidirectional camera capable of recording light informat ...

Segment-Based Real-Time Stereo Vision Matching using Characteristics Vectors

Jean-Philippe Thiran

Stereo vision is a usual method to obtain depth information from images. The problems encountered when applying well established algorithms to real-time applications are due to the high computational load required. In this article we address this issue by ...

Extrinsic RGB-D camera calibration for legged robots

Roland Siegwart, Marco Hutter

This paper describes a method to identify the extrinsic parameters of RGB-D cameras mounted on legged robots. Since the calculation of the parameters is based on the detection of the robots feet in the camera images, no special calibration objects are requ ...

Extraction and Classification of Handwritten Annotations

Pierre Dillenbourg, Frédéric Kaplan, Andrea Mazzei

This article describes a method for extracting and classifying handwritten annotations on printed documents using a simple camera integrated in a lamp or a mobile phone. The ambition of such a research is to offer a seamless integration of notes taken on p ...

Plenoptic based super-resolution for omnidirectional image sequences

Pascal Frossard, Pierre Vandergheynst, Luigi Bagnato

This paper addresses the reconstruction of high resolution omnidirectional images from a low resolution video acquired by an omnidirectional camera moving in a static scene. In order to exploit the additional information provided by the side images in the ...

The Robot Vision Track at ImageCLEF 2010

Barbara Caputo, Marco Fornoni

This paper describes the robot vision track that has been proposed to the ImageCLEF 2010 participants. The track addressed the problem of visual place classification, with a special focus on generalization. Participants were asked to classify rooms and are ...

On Pixel Detection Threshold in the Gigavision Camera

Martin Vetterli, Edoardo Charbon, Sabine Süsstrunk, Luciano Sbaiz, Feng Yang

Recently, we have proposed a new image device called gigavision camera whose most important characteristic is that pixels have binary response. The response function of a gigavision sensor is non-linear and similar to a logarithmic function, which makes th ...

Disparity Search Range Estimation: Enforcing Temporal Consistency

Zafer Arican

This paper presents a new approach for estimating the disparity search range in stereo video that enforces temporal consistency. Reliable search range estimation is very important since an incorrect estimate causes most stereo matching methods to get trapp ...

Imaging of turbulent structures and tomographic reconstruction of TORPEX plasma emissivity

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Davoud Iraji

In the TORPEX [ A. Fasoli et al., Phys. Plasmas 13, 055902 (2006) ], a simple magnetized plasma device, low frequency electrostatic fluctuations associated with interchange waves, are routinely measured by means of extensive sets of Langmuir probes. To com ...
