BMC Musculoskeletal Disorders, 2018 Background Musculoskeletal models are commonly used to quantify joint motions and loads during human motion. Constraining joint kinematics simplifies these models but the implications of the placement and quantity of markers used during data acquisition ...

Hierarchical Motion Understanding via Motion Programs [PDF]
arXiv, 2021 Current approaches to video analysis of human motion focus on raw pixels or keypoints as the basic units of reasoning. We posit that adding higher-level motion primitives, which can capture natural coarser units of motion such as backswing or follow-through, can be used to improve downstream analysis tasks.

Energy cost and return for hunting in African wild dogs and cheetahs
Nature Communications, 2016 The long-distance hunting behaviour of African wild dogs is thought to be energetically costly. Here, Hubel et al. show that multiple opportunistic short-distance hunts and group feeding make African wild dogs in mixed woodland savannah energetically ...

Do running speed and shoe cushioning influence impact loading and tibial shock in basketball players? [PDF]
PeerJ, 2018 Background Tibial stress fracture (TSF) is a common injury in basketball players. This condition has been associated with high tibial shock and impact loading, which can be affected by running speed, footwear condition, and footstrike pattern.

MultiAct: Long-Term 3D Human Motion Generation from Multiple Action Labels [PDF]
arXiv, 2022 We tackle the problem of generating long-term 3D human motion from multiple action labels. Two main previous approaches, such as action- and motion-conditioned methods, have limitations to solve this problem. The action-conditioned methods generate a sequence of motion from a single action.

Retrospective Motion Correction in Gradient Echo MRI by Explicit Motion Estimation Using Deep CNNs [PDF]
arXiv, 2023 Magnetic Resonance Imaging allows high resolution data acquisition with the downside of motion sensitivity due to relatively long acquisition times. Even during the acquisition of a single 2D slice, motion can severely corrupt the image. Retrospective motion correction strategies do not interfere during acquisition time but operate on the motion ...

2019 IEEE/CVF International Conference on Computer Vision (ICCV), 2019 Sounds originate from object motions and vibrations of surrounding air. Inspired by the fact that humans is capable of interpreting sound sources from how objects move visually, we propose a novel system that explicitly captures such motion cues for the task of sound localization and separation.

Motion of the Esophagus Due to Cardiac Motion
PLoS ONE, 2014 When imaging studies (e.g. CT) are used to quantify morphological changes in an anatomical structure, it is necessary to understand the extent and source of motion which can give imaging artifacts (e.g. blurring or local distortion). The objective of this study was to assess the magnitude of esophageal motion due to cardiac motion.
