Role of Holographic Displays and Stereovision Displays in Patient Safety and Robotic Surgery

Hannes Bleuler, Telmo David Ribeiro Da Costa

In this study, the role of different 3D vision systems on the patient safety in the context of robotic surgery was studied. Clearly safety is the foremost importance in all surgical procedures. It is well studied in the clinical surgical procedures but the ...

The PANOPTIC Camera: A Plenoptic Sensor with Real-Time Omnidirectional Capability

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

A new biologically-inspired vision sensor made of one hundred "eyes" is presented, which is suitable for real-time acquisition and processing of 3-D image sequences. This device, named the Panoptic camera, consists of a layered arrangement of approximately ...

Patch-based methods for variational image processing problems

Emmanuel D'Angelo

Image Processing problems are notoriously difficult. To name a few of these difficulties, they are usually ill-posed, involve a huge number of unknowns (from one to several per pixel!), and images cannot be considered as the linear superposition of a few p ...

Laplacian Meshes for Monocular 3D Shape Recovery

Pascal Fua, Aydin Varol, Jonas Olof Martin Östlund, Tien Dat Ngo

We show that by extending the Laplacian formalism, which was first introduced in the Graphics community to regularize 3D meshes, we can turn the monocular 3D shape reconstruction of a deformable surface given correspondences with a reference image into a w ...

Enhanced Omnidirectional Image Reconstruction Algorithm and its Real-Time Hardware

Alexandre Schmid, Yusuf Leblebici, Hossein Afshari, Abdulkadir Akin

Omnidirectional stereoscopy and depth estimation are complex problems of image processing to which the Panoptic camera offers a novel solution. The Panoptic camera is a biologically-inspired vision sensor made of multiple cameras. It is a polydioptric syst ...

Gradient Response Maps for Real-Time Detection of Textureless Objects

Pascal Fua, Slobodan Ilic, Vincent Lepetit

We present a method for real-time 3D object instance detection that does not require a time-consuming training stage, and can handle untextured objects. At its core, our approach is a novel image representation for template matching designed to be robust t ...

Resolving Ambiguities in Monocular 3D Reconstruction of Deformable Surfaces

Aydin Varol

In this thesis, we focus on the problem of recovering 3D shapes of deformable surfaces from a single camera. This problem is known to be ill-posed as for a given 2D input image there exist many 3D shapes that give visually identical projections. We present ...

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 ...

Motion Parallax Based Restitution of 3D Images on Legacy Consumer Mobile Devices

Touradj Ebrahimi, Jong Seok Lee, Lutz Goldmann, Martin Rerabek

While 3D display technologies are already widely available for cinema and home or corporate use, only a few portable devices currently feature 3D display capabilities. Moreover, the large majority of 3D display solutions rely on binocular perception. In th ...
