Evaluating the Reliability and Consistency of Treadmill Gait Analysis Using an RGB-D Camera: Effects of Assistance and No Assistance

Sensors
This study aimed to assess the intraday reliability of markerless gait analysis using an RGB-D camera versus a traditional three-dimensional motion analysis (3DMA) system with and without a simulated walking assistant.

Reliability, agreement and variability of a markerless computer vision algorithm for equine gait analysis under field conditions

Equine Veterinary Journal, EarlyView.
Abstract Background Computer vision‐based algorithms offer accessible alternatives for equine gait analysis but require thorough assessment under diverse conditions. Objectives To evaluate a proprietary vision‐based algorithm's reliability in measuring vertical displacement signals (VDS) at the eye, withers and croup, alongside groundline estimation ...

Parallelization strategies for markerless human motion capture

Journal of Real-Time Image Processing, 2014
Markerless Motion Capture (MMOCAP) is the problem of determining the pose of a person from images captured by one or several cameras simultaneously without using markers on the subject. Evaluation of the solutions is frequently the most time-consuming task, making most of the proposed methods inapplicable in real-time scenarios.

Extended Reality in Endodontics: A Review of Current Applications and Future Potential

International Endodontic Journal, EarlyView.
ABSTRACT Background Extended reality (XR) technologies, encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), are increasingly used in endodontic education and practice. A gap exists regarding understanding of XR's applications and limitations among endodontic educators and practitioners.

Markerless motion capture provides accurate predictions of ground reaction forces across a range of movement tasks

Measuring or estimating the forces acting on the human body during movement is critical for determining the biomechanical aspects relating to injury, disease and healthy ageing.

Markerless motion capture of man-machine interaction

2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008
This work deals with modeling and markerless tracking of athletes interacting with sports gear. In contrast to classical markerless tracking, the interaction with sports gear comes along with joint movement restrictions due to additional constraints: while humans can generally use all their joints, interaction with the equipment imposes a coupling ...

Autonomous Frameless Spine Registration and Robot‐Assisted Surgery

Orthopaedic Surgery, EarlyView.
Workflow of a contactless, frame‐free, robot‐assisted vertebra registration system. Preoperative CT data establish vertebra {V} and mask {Mpre} coordinate systems. Their relationship is computed, and intraoperatively the robot recognizes the skin‐affixed mask, defining {Mintra}.

Markerless tracking using planar structures in the scene

Proceedings IEEE and ACM International Symposium on Augmented Reality (ISAR 2000), 2002
We describe a markerless camera tracking system for augmented reality that operates in environments which contain one or more planes. This is a common special case, which we show significantly simplifies tracking. The result is a practical, reliable, vision-based tracker.

Transcutaneous auricular vagus nerve stimulation during short‐term motor practice drives cortical plasticity without behavioural improvement

The Journal of Physiology, EarlyView.
Abstract figure legend Transcutaneous auricular vagus nerve stimulation (taVNS) was applied during short‐term dexterous motor practice to examine its effects on behavioural performance and neural plasticity. Healthy participants practiced a two‐ball rotation task while receiving taVNS or sham stimulation.
