Meaningful matches in stereovision

N Sabater, A Almansa, JM Morel - IEEE transactions on pattern …, 2011 - ieeexplore.ieee.org
This paper introduces a statistical method to decide whether two blocks in a pair of images
match reliably. The method ensures that the selected block matches are unlikely to have …

A-contrario modeling for robust localization using raw GNSS data

S Zair, S Le Hégarat-Mascle… - IEEE Transactions on …, 2015 - ieeexplore.ieee.org
In Global Navigation Satellite System (GNSS) positioning, urban environments represent an
issue particularly because of multipath and nonline-of-sight effects. The latter effects induce …

Outlier detection in GNSS pseudo-range/Doppler measurements for robust localization

S Zair, S Le Hégarat-Mascle, E Seignez - Sensors, 2016 - mdpi.com
In urban areas or space-constrained environments with obstacles, vehicle localization using
Global Navigation Satellite System (GNSS) data is hindered by Non-Line Of Sight (NLOS) …

Efficient evaluation of the number of false alarm criterion

S Le Hégarat-Mascle, E Aldea, J Vandoni - EURASIP Journal on Image …, 2019 - Springer
This paper proposes a method for computing efficiently the significance of a parametric
pattern inside a binary image. On the one hand, a-contrario strategies avoid the user …

Automatically finding clusters in normalized cuts

M Tepper, P Musé, A Almansa, M Mejail - Pattern Recognition, 2011 - Elsevier
Normalized Cuts is a state-of-the-art spectral method for clustering. By applying spectral
techniques, the data becomes easier to cluster and then k-means is classically used …

A Helmholtz principle approach to parameter free change detection and coherent motion using exchangeable random variables

A Flenner, G Hewer - SIAM Journal on Imaging Sciences, 2011 - SIAM
A parameter free technique for finding changes between images is discussed. The
technique uses the Helmholtz principle to find changes in an input image in situations where …

A biclustering framework for consensus problems

M Tepper, G Sapiro - SIAM Journal on Imaging Sciences, 2014 - SIAM
We consider grou** as a general characterization for problems such as clustering,
community detection in networks, and multiple parametric model estimation. We are …

A contrario edge detection with edgelets

N Widynski, M Mignotte - 2011 IEEE International Conference …, 2011 - ieeexplore.ieee.org
Edge detection remains an active problem in the image processing community, because of
the high complexity of natural images. In the last decade, Desolneux et al. proposed a novel …

A contrario selection of optimal partitions for image segmentation

J Cardelino, V Caselles, M Bertalmio, G Randall - SIAM Journal on Imaging …, 2013 - SIAM
We present a novel segmentation algorithm based on a hierarchical representation of
images. The main contribution of this work is to explore the capabilities of the a contrario …

Detection and identification of elliptical structure arrangements in images: theory and algorithms

V Pătrăucean - 2012 - theses.hal.science
This thesis deals with different aspects concerning the detection, fitting, and identification of
elliptical features in digital images. We put the geometric feature detection in the a contrario …
