ROSMAP-Compass: A data-harmonised, AI-ready atlas of 22 million single nuclei from the ROSMAP cohort Open
The Religious Orders Study and Memory and Aging Project (ROSMAP) cohort has generated the world's most comprehensive single-cell transcriptomic resource for Alzheimer's disease research. Naturally, in a project spanning multiple years with…
DicePlot: A package for high dimensional categorical data visualization Open
Summary Visualization of multidimensional, categorical data is a common challenge across scientific domains and, in particular, the life sciences. The goal is to create a comprehensive overview of the underlying data which enables one to a…

LumEDA: image luminance based contactless correlates of electrodermal responses Open
Objective . Electrodermal activity (EDA) is a marker of psychophysiological arousal and is usually a measure of the skin conductance which is associated with sweat gland activity. Recent studies have shown that it is possible to estimate t…
T-FAKE: Synthesizing Thermal Images for Facial Landmarking Open
Facial analysis is a key component in a wide range of applications such as healthcare, autonomous driving, and entertainment. Despite the availability of various facial RGB datasets, the thermal modality, which plays a crucial role in life…
LumEDA: Image Luminance Based Contactless Correlates of Electrodermal Responses Open
This work builds upon the findings of a 2020 pilot study which for the first time showed that correlates of electrodermal activity (EDA) could be estimated using simple spatial filters on video data captured under special lighting conditio…
Lagrangian motion magnification with double sparse optical flow decomposition Open
Microexpressions are fast and spatially small facial expressions that are difficult to detect. Therefore, motion magnification techniques, which aim at amplifying and hence revealing subtle motion in videos, appear useful for handling such…

Electrodermal Responses to Driving Maneuvers in a Motion Sickness Inducing Real-World Driving Scenario Open
Motion sickness is a phenomenon attracting increasing attention with the ever-growing popularity of highly automated driving. Understanding motion sickness is of significant interest in the context of self-driven vehicles because, in this …
Software for <span>non‐parametric</span> image registration of <span>2‐photon</span> imaging data Open
Functional 2‐photon microscopy is a key technology for imaging neuronal activity. The recorded image sequences, however, can contain non‐rigid movement artifacts which requires high‐accuracy movement correction. Variational optical flow (O…

Multimodal data acquisition at <span>SARS‐CoV</span> ‐2 drive through screening centers: Setup description and experiences in Saarland, Germany Open
SARS‐CoV‐2 drive through screening centers (DTSC) have been implemented worldwide as a fast and secure way of mass screening. We use DTSCs as a platform for the acquisition of multimodal datasets that are needed for the development of remo…

Vestigial auriculomotor activity indicates the direction of auditory attention in humans Open
Unlike dogs and cats, people do not point their ears as they focus attention on novel, salient, or task-relevant stimuli. Our species may nevertheless have retained a vestigial pinna-orienting system that has persisted as a 'neural fossil’…
Towards Contactless Estimation of Electrodermal Activity Correlates Open
This paper presents a proof-of-concept for contactless and nonintrusive estimation of electrodermal activity (EDA) correlates using a camera. RGB video of the palm under three different lighting conditions showed that for a suitably chosen…
Fast Variational Alignment of non-flat 1D Displacements for Applications in Neuroimaging Open
Background In the context of signal analysis and pattern matching, alignment of 1D signals for the comparison of signal morphologies is an important problem. For image processing and computer vision, 2D optical flow (OF) methods find wide …

Vestigial Auriculomotor Activity Indicates the Direction of Auditory Attention in Humans Open
It is commonly assumed that, unlike dogs and cats, we humans do not make ear movements when focusing our attention reflexively toward novel sounds or voluntarily toward those that are goal–relevant. In fact, it has been suggested that we d…
