Deep eyes: Joint depth inference using monocular and binocular cues

Human visual system relies on both monocular focusness cues and binocular stereo cues to gain effective 3D perception. Correspondingly, depth from focus/defocus (DfF/DfD) and stereo matching are two most studied passive depth sensing schemes, which are tra ...

MonStereo: When Monocular and Stereo Meet at the Tail of 3D Human Localization

Alexandre Massoud Alahi, Sven Kreiss, Taylor Ferdinand Mordan, Lorenzo Bertoni

Monocular and stereo visions are cost-effective solutions for 3D human localization in the context of self-driving cars or social robots. However, they are usually developed independently and have their respective strengths and limitations. We propose a no ...

Learning stereo reconstruction with deep neural networks

Stepan Tulyakov

Stereo reconstruction is a problem of recovering a 3d structure of a scene from a pair of images of the scene, acquired from different viewpoints. It has been investigated for decades and many successful methods were developed. The main drawback of these ...

Graph-Based Representation and Coding of Multiview Images

Pascal Frossard, Bénédicte Motz

Instead of lossily coding depth images resulting in undesirable geometric distortion, graph-based representation (GBR) describes disparity information as a graph with a controllable accuracy. In this paper, we propose a more compact graphical representatio ...

Subjective evaluation of two stereoscopic imaging systems exploiting visual attention to improve 3D quality of experience

Touradj Ebrahimi, Philippe Hanhart

Crosstalk and vergence-accommodation rivalry negatively impact the quality of experience (QoE) provided by stereoscopic displays. However, exploiting visual attention and adapting the 3D rendering process on the fly can reduce these drawbacks. In this pape ...

Method and apparatus for identifying local features

Martin Vetterli, Alireza Ghasemi, Laurent Michel Rime

A method of local feature identification, comprising the steps of: retrieving data representing a lightfield (101); forming an epipolar volume (V) from the retrieved data; applying a transform to epipolar planes retrieved from said epipolar volume, so as t ...

Compressed look-up-table based real-time rectification hardware

Alexandre Schmid, Yusuf Leblebici, Abdulkadir Akin, Luis Manuel Gaemperle, Ipek Baz

Stereo image rectification is a pre-processing step of disparity estimation intended to remove image distortions and to enable stereo matching along an epipolar line. A real-time disparity estimation system needs to perform real-time rectification which re ...

Fast encoding techniques for Multiview Video Coding

Pascal Frossard

Multiview Video Coding (MVC) is a technique that permits efficient compression of multiview video. MVC uses variable block size motion and disparity estimation for block matching. This requires an exhaustive search process that involves all possible macro- ...

Assessment of Stereoscopic Crosstalk Perception

Touradj Ebrahimi

Stereoscopic three-dimensional (3-D) services do not always prevail when compared with their two-dimensional (2-D) counterparts, though the former can provide more immersive experience with the help of binocular depth. Various specific 3-D artefacts might ...

Distributed Representation of Geometrically Correlated Images with Compressed Linear Measurements

Pascal Frossard, Vijayaraghavan Thirumalai

The distributed representation of correlated images is an important challenge in applications such as multi-view imaging in camera networks or low complexity video coding. This paper addresses the problem of distributed coding of images whose correlation i ...

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

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

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 ...

Dense Disparity Estimation from Linear Measurements

Pascal Frossard, Vijayaraghavan Thirumalai

This paper proposes a methodology to estimate the correlation model between a pair of images that are given under the form of linear measurements. We consider an image pair whose common objects are relatively displaced due to the positioning of vision sens ...

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

Michael Herzog, Bilge Sayim

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 ...

Coarse scene geometry estimation from sparse approximations of multi-view omnidirectional images

Pascal Frossard, Ivana Tosic

This paper presents a framework for coarse scene geometry estimation, based on sparse representations of omnidirectional images with geometrical basis functions. We introduce a correlation model that relates sparse components in different views with local ...
