Fuck this has been out since Oct. 2005. Our fucking failures of everything in stroke have had enough time to create objective analysis of gait disturbances and map stroke protocols to fix them. But NO, they are lazily waiting for SOMEONE ELSE TO SOLVE THE PROBLEM?
Markerless Human Motion Capture for Gait Analysis
(Submitted on 21 Oct 2005)
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 model and particle filtering are basic elements of our approach. No dynamic model is used thus this system can be described as generic and simple to implement. A modified particle filtering algorithm, which we call Interval Particle Filtering, is used to reorganise and search through the model's configurations search space in a deterministic optimal way. This algorithm was able to perform human movement tracking with success. Results from the treatment of a single cam feeds are shown and compared to results obtained using a marker based human motion capture system.
