A reversible data hiding method for encrypted images

…, M Chaumont, O Strauss - … , and watermarking of …, 2008 - spiedigitallibrary.org
Since several years, the protection of multimedia data is becoming very important. The
protection of this multimedia data can be done with encryption or data hiding algorithms. To …

Two-level QR code for private message sharing and document authentication

…, W Puech, C Destruel, O Strauss… - IEEE Transactions …, 2015 - ieeexplore.ieee.org
The quick response (QR) code was designed for storage information and high-speed reading
applications. In this paper, we present a new rich QR code that has two storage levels and …

A robot-assisted imaging pipeline for tracking the growths of maize ear and silks in a high-throughput phenotyping platform

N Brichet, C Fournier, O Turc, O Strauss, S Artzet… - Plant Methods, 2017 - Springer
Background In maize, silks are hundreds of filaments that simultaneously emerge from the
ear for collecting pollen over a period of 1–7 days, which largely determines grain number …

[HTML][HTML] Generalizing the Wilcoxon rank-sum test for interval data

J Perolat, I Couso, K Loquin, O Strauss - International Journal of …, 2015 - Elsevier
Here we propose an adaption of Wilcoxon's two-sample rank-sum test to interval data. This
adaption is interval-valued: it computes the minimum and maximum values of the statistic …

A flexible targetless LiDAR–GNSS/INS–camera calibration method for UAV platforms

…, P Kennel, T Allouis, C Fiorio, O Strauss - ISPRS Journal of …, 2020 - Elsevier
There is a growing need for 3D colored maps acquired from multi-sensor moving platforms.
Accurate multi-sensor data alignment is an important prerequisite for the construction of 3D …

[HTML][HTML] Integrating imprecise data in generative models using interval-valued Variational Autoencoders

L Sánchez, N Costa, I Couso, O Strauss - Information Fusion, 2025 - Elsevier
Variational Autoencoders (VAEs) enable the integration of diverse data sources into a
unified latent representation, facilitating the fusion of information from various inputs and the …

Ghost detection and removal in high dynamic range images

D Sidibe, W Puech, O Strauss - 2009 17th European Signal …, 2009 - ieeexplore.ieee.org
A classic approach to obtain High Dynamic Range Images (HDRI) consists in combining
multiple images of the same scene with varying exposures. However, if the scene is not static …

Color noise correlation-based splicing detection for image forensics

V Itier, O Strauss, L Morel, W Puech - Multimedia Tools and Applications, 2021 - Springer
Today, it has become very easy to manipulate digital images using image processing tools
and software such as Adobe Photoshop ( https://www.adobe.com/products/photoshop.html ). …

Kendall's rank correlation on quantized data: an interval-valued approach

I Couso, O Strauss, H Saulnier - Fuzzy Sets and Systems, 2018 - Elsevier
Kendall's rank correlation coefficient, also called Kendall's τ, is an efficient and robust way
for identifying monotone relationships between two data sequences. However, when applied …

Giant extinct caiman breaks constraint on the axial skeleton of extant crocodylians

TM Scheyer, JR Hutchinson, O Strauss, M Delfino… - Elife, 2019 - elifesciences.org
The number of precaudal vertebrae in all extant crocodylians is remarkably conservative,
with nine cervicals, 15 dorsals and two sacrals, a pattern present also in their closest extinct …
