Researchers at Nanyang Technological College, Singapore (NTU Singapore) have showcased a camera-based movement seize system designed to watch sufferers throughout rehabilitation consultations and extra — with out the necessity to apply markers.
“Our software might be utilized by professionals in a number of fields. For instance, medical doctors and therapists may probably use it to objectively analyze their sufferers’ actions,” explains Prayook Jatesiktat, PhD, analysis fellow on the Rehabilitation Analysis Institute of Singapore (RRIS) and lead on the mission.
“The know-how may additionally profit athletes and coaches, because it offers them entry to an easy-to-use movement seize system to evaluate their sports-related actions. Animators may additionally use our know-how to drive their characters’ actions.”
Dubbed Exact Marker-less, the seize system is ready to observe bone landmark areas inside 10-15mm (round 0.4-0.6″), while not having the appliance of markers as with most movement seize programs providing related accuracy. The outcome, the workforce claims, is a system that can be utilized with simply minutes of set-up time and which permits for extra pure motion to be captured.
The strategy makes use of machine studying, educated on over 16TB of photographs monitoring the actions of a 150-subject cohort, to successfully calculate the place the markers can be if the themes have been sporting them. Photographs are captured utilizing two to 4 normal cameras linked to a pc, whereas a calibration package retains every thing ticking over.

“To sharpen the precision of such a mannequin, we harnessed the facility of machine studying to coach a computation mannequin to foretell the placement of markers on video footage of a transferring topic,” explains Ang Wei Tech, affiliate professor and govt director at RRIS.
“The know-how developed by our workforce enhances the precision rehabilitation analysis at RRIS, which harnesses information analytics and pc simulations to allow the interpretation of such analysis work to the precise medical apply.”
The workforce has confirmed that “a number of Singapore-based firms” have expressed curiosity in commercializing the know-how, whereas a patent has been utilized for.
