Skeletal Parameter Estimation from Optical Motion Capture Data [PDF]
2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2004 In this paper we present an algorithm for automatically estimating a subject’s skeletal structure from optical motion capture data. Our algorithm consists of a series of steps that cluster markers into segment groups, determine the topological connectivity between these groups, and locate the positions of their connecting joints.

Multiple Hypothesis Tracking for Automatic Optical Motion Capture [PDF]
, 2002 We present a technique for performing the tracking stage of optical motion capture which retains, at each time frame, multiple marker association hypotheses and estimates of the subject's position. Central to this technique are the equations for calculating the likelihood of a sequence of association hypotheses, which we develop using a Bayesian ...

Analysis of Kinematics of Flapping Wing UAV Using OptiTrack Systems
Aerospace, 2016 An analysis of the kinematics of a flapping membrane wing using experimental kinematic data is presented. This motion capture technique tracks the positon of the retroreflective marker(s) placed on the left wing of a 1.3-m-wingspan ornithopter.

Triggered optical coherence tomography for capturing rapid periodic motion [PDF]
Scientific Reports, 2011 Quantitative cross-sectional imaging of vocal folds during phonation is potentially useful for diagnosis and treatments of laryngeal disorders. Optical coherence tomography (OCT) is a powerful technique, but its relatively low frame rates makes it challenging to visualize rapidly vibrating tissues. Here, we demonstrate a novel method based on triggered
