Assessment of spatiotemporal gait parameters using a deep learning algorithm-based markerless motion capture system
نویسندگان
چکیده
Spatiotemporal parameters can characterize the gait patterns of individuals, allowing assessment their health status and detection clinically meaningful changes in gait. Video-based markerless motion capture is a user-friendly, inexpensive, widely applicable technology that could reduce barriers to measuring spatiotemporal clinical more diverse settings. Two studies were performed determine whether measured using demonstrate concurrent validity with those marker-based pressure-sensitive mat. For first study, thirty healthy young adults treadmill at self-selected speeds while synchronized video data recorded simultaneously. second twenty-five over-ground footfalls mat Kinematic heel-strike toe-off events used identify same cycles between systems. Nine by each system directly compared Measurements Bland-Altman methods, mean differences, Pearson correlation coefficients, intraclass coefficients. The results indicate measurements have good excellent agreement systems, except for stance time double limb support relative both systems stride width These findings adequately measure during

Markerless Human Motion Capture for Gait Analysis
The aim of our study is to detect balance disorders and a tendency towards the falls in the elderly, knowing gait parameters. In this paper we present a new tool for gait analysis based on markerless human motion capture, from camera feeds. The system introduced here, recovers the 3D positions of several key points of the human body while walking. Foreground segmentation, an articulated body mo...
متن کاملKinematic parameters of throwing performance in patients with schizophrenia using a markerless motion capture system.
Motor dysfunction is consistently reported but understudied in schizophrenia. It has been hypothesized that this abnormality may reflect a neuro-developmental disorder underlying this illness. The main goal of this study was to analyze movement patterns used by participants with schizophrenia and healthy controls during overarm throwing performance, using a markerless motion capture system. Thi...
متن کاملMarkerless Based Human Motion Capture: A Survey
This literature survey attempts to recent developments and current state-of-the-art in the field of body analysis by the use of non-intrusive optical systems. Markerless based human motion capture describes the activity of analysing and expressing human motion in mathematical terms. The survey shows that the task of motion capture can be divided into a number of systematically distinct groups, ...
