Sustained invisibility through crowding and continuous flash suppression: a comparative review

The study of non-conscious vision benefits from several alternative methods that allow the suppression of an image from awareness. Here, we present and compare two of them that are particularly well-suited for creating sustained periods of invisibility, na ...

Quadtree Structured Image Approximation for Denoising and Interpolation

Adam James Scholefield, Pier Luigi Dragotti

The success of many image restoration algorithms is often due to their ability to sparsely describe the original signal. Shukla et al. proposed a compression algorithm, based on a sparse quadtree decomposition model, which could optimally represent piecewi ...

Measuring the Dynamics of Contrast & Daylight Variability in Architecture: A Proof of Concept Methodology

Marilyne Andersen, Siobhan Francois Rockcastle

Unlike artificial light sources, which can be calibrated to meet a desired luminous effect regardless of latitude, climate, or time of day, daylight is a dynamic light source, which produces variable shadow patterns and fluctuating levels of brightness. Wh ...

Efficient scanning for em based target localization

Pascal Fua, Graham Knott, Raphael Sznitman, Aurélien Lucchi

We presented an approach for speeding-up image acquisition when tasked with localizing specific structures in FIB-SEM imagery. It exploits the fact that low-quality images can be acquired faster than higher-quality ones and yet be sufficient for inference ...

Ultrasound Fourier Slice Imaging: a novel approach for ultrafast imaging technique

Jean-Philippe Thiran, Olivier Bernard

Ultrafast imaging based on plane-wave (PW) has become an intense area of research thanks to its capability of reaching frame rate higher than a thousand of frames per second. Several proposed approaches are based on Fourier-domain reconstruction. In these ...

Prime Power Terms In Elliptic Divisibility Sequences

Valéry Aurélien Mahé

We study a problem on specializations of multiples of rational points on elliptic curves analogous to the Mersenne problem. We solve this problem when descent via isogeny is possible by giving explicit bounds on the indices of prime power terms in elliptic ...

Three-dimensional super-resolution structured illumination microscopy with maximum a posteriori probability image estimation

Tomas Lukes

We introduce and demonstrate a new high performance image reconstruction method for super-resolution structured illumination microscopy based on maximum a posteriori probability estimation (MAP-SIM). Imaging performance is demonstrated on a variety of fluo ...

Tubular Geodesics using Oriented Flux: An ITK Implementation

Pascal Fua, Engin Türetken, Fethallah Benmansour

This document describes an ITK implementation of an interactive method for tracing curvilinear structures. The basic tools provided in this framework are an oriented flux-based tubularity measure and a geodesic path tracer that uses the fast marching algor ...

Improved Local Binary Pattern Based Action Unit Detection Using Morphological and Bilateral Filters

Jean-Philippe Thiran, Matteo Sorci, Anil Yuce

Automatic facial action unit (AU) detection in videos is the key ingredient to all systems that utilize a subject face for either interaction or analysis purposes. With the ever growing range of possible applications, achieving a high accuracy in the simpl ...

Semi-Automated Reconstruction of Curvilinear Structures in Noisy 2D images and 3D image stacks

Pascal Fua, Engin Türetken, Fethallah Benmansour

We propose a new approach to semi-automated delineation of curvilinear structures in a wide range of imaging modalities. Earlier approaches lack robustness to imaging noise, do not provide radius estimates for the structures and operate only on single chan ...
