Robust image reconstruction from multi-view measurements

Pierre Vandergheynst, Gilles Puy

We propose a novel method to accurately reconstruct a set of images representing a single scene from few linear multi-view measurements. Each observed image is modeled as the sum of a background image and a foreground one. The background image is common to ...

3D high-density localization microscopy using hybrid astigmatic/biplane imaging and sparse image reconstruction

Michaël Unser, Suliana Manley, Seamus John Holden, Lina Carlini

Localization microscopy achieves nanoscale spatial resolution by iterative localization of sparsely activated molecules, which generally leads to a long acquisition time. By implementing advanced algorithms to treat overlapping point spread functions (PSFs ...

Computationally efficient background subtraction in the light field domain

Martin Vetterli, Mahdad Hosseini Kamal, Alireza Ghasemi

Since the invention of first camera, people have always thought of new ways to capture moments. With the advent of digital photography, not only imaging systems have progressed, but also technology provides new user experience. The recently introduced ligh ...

Image reconstruction of non-planar scenes from compressed multi-view measurements

Pierre Vandergheynst, Gilles Puy

We extend the domain of application of a method developed recently for joint reconstruction of l images, representing the same scene, from few multi-view measurements. While this method was initially designed for planar scenes, we show here that parametric ...

IMAGING The fog clears

Demetri Psaltis

A technique has been developed to image a fluorescent object hiding behind a light-scattering screen without the need for a detector behind the screen. The approach could find applications in imaging biological tissue. ...

Coherent Anti-Stokes Raman Scattering Holography: Theory And Experiment

Demetri Psaltis

We review coherent anti-Stokes Raman scattering (CARS) holography as a non-scanning, label-free, three-dimensional imaging technique. The theory of CARS and its integration with digital holography is explored. We then discuss the experimental implementatio ...

Object Duplicate Detection

Péter Vajda

With the technological evolution of digital acquisition and storage technologies, millions of images and video sequences are captured every day and shared in online services. One way of exploring this huge volume of images and videos is through searching a ...

Omnidirectional Object Duplicate Detection

Touradj Ebrahimi, Lutz Goldmann, Ivan Ivanov, Péter Vajda

In this paper, we extend a graph-based approach for omnidirectional object duplicate detection in still images. Objects are detected from several points of view with different distances. The goal of this work is to determine how many training images have t ...

Digital reverse propagation in focusing Kerr media

Demetri Psaltis, Alexandre Goy

Lenses allow the formation of clear images in homogeneous linear media. Holography is an alternative imaging method, but its use is limited to cases in which it provides an advantage, such as three-dimensional imaging. In nonlinear media, lenses no longer ...

Estimation of Phase in Fringe Projection Technique Using High-order Instantaneous Moments Based Method

Pramod Rastogi, Sai Siva Gorthi

For three-dimensional (3D) shape measurement using fringe projection techniques, the information about the 3D shape of an object is encoded in the phase of a recorded fringe pattern. The paper proposes a high-order instantaneous moments based method to est ...
