EMG-based 3D hand gesture prediction using transformer–encoder classification

ICT Express, 2023
One of the most common task of electromyography (EMG)-based human–machine interface (HMI) is the hand gesture recognition. Robust and accurate predictions leveraging the surface EMG (sEMG) is a key challenge.

Validation of a handheld smartphone markerless gait‐analysis tool using an estimated groundline in horses

Equine Veterinary Journal, EarlyView.
Abstract Background A handheld smartphone‐based computer vision algorithm (RealHorse® [RH]) offers accessible alternatives for equine gait analysis but requires validation against a gold‐standard three‐dimensional multicamera optical motion capture system (Qualisys® [QS]).

Learning to Estimate 3D Hand Pose from Single RGB Images

, 2017
Low-cost consumer depth cameras and deep learning have enabled reasonable 3D hand pose estimation from single depth images. In this paper, we present an approach that estimates 3D hand pose from regular RGB images.

Clinical Algorithm‐Guided Approach to Botulinum Toxin Type A Treatment for Axial Postural Abnormalities in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Axial postural abnormalities (APAs) are common, disabling complications of Parkinson's disease (PD) with unclear pathophysiology. The presence of hyperactivity in multiple trunk muscles supports the use of botulinum toxin (BTA). However, its application is complex, due to the lack of standardized clinical and electrophysiological ...
