Background Adolescent girls with AN undergo high levels of stress, which has been shown as risk factor in the development of eating disorders. Widely examined autonomic indices for stress reactivity are heart rate (HR) and heart rate variability (HRV, R-R intervals (RRI) in electrocardiogram). T... Continue

Background A commonly known problem with accelerometers, inertial sensors or other measurement systems based on sensors attached to the skin are signal distortions or artefacts caused by vibration of the skin and soft tissues. To accurately measure acceleration/angular velocity during movement, ... Continue

Adolescent girls with AN undergo high levels of stress, which has been shown as risk factor in the development of eating disorders. Widely examined autonomic indices for stress reactivity are heart rate (HR) and heart rate variability (HRV, RR intervals (RRI) in electrocardiogram). The current stat... Continue

Background Dental problems are one of the most prevalent clinical conditions. While oral care method have improved substantially over the last 100 years, incidence rates of tooth and gum problems are persisting or even increasing. For example, bacteria acids erode the tough tooth enamel and subs... Continue

Background 3D photometric reconstruction is a powerful approach to represent organs or body parts digitally. Various machine learning (ML)-pipelines for reconstruction assume rigid bodies or colour differences to estimate depth information. Yet other techniques use depth cameras, e.g. as built i... Continue

Background Inertial measurement units (IMUs) enable biomechanists and rehabilitation researchers to continuously measure the kinematics of a variety of humans in their natural environment, thereby improving our understanding of human movement pathology. Previous studies have computed IMU-based e... Continue

Background From a classical marker-based motion capture system (MoCap) you obtain the coordinates of placed markers, which are used to establish a biomechanical model. However, information of the subject's circumferences (silhouette) and surface effects is not provided, which is crucial in case ... Continue

Background Today's data collection usually uses different types of sensors that store data in different formats. Therefore, a well-structured database is a useful tool for further processing of the data. Especially in context recognition tasks, annotating the merged data plays a key role in bein... Continue

Background: To automate the analysis of consumed food for dietary monitoring, several approaches have been tried. Two promising ideas are a) electromyographic (EMG) monitoring of the masseter muscle, and b) acoustic measurements to capture chewing sounds. While EMG data can be used well for segment... Continue
