Paper Abstract

The Naval Biodynamics Laboratory (NBDL) in New Orleans is investigating the human response to different acceleration environments. In controlled experiments rigid clusters of targets are attached to specific anatomical segments of human volunteers and photographed by at least two high-speed cinematographic cameras. The x,y coordinates of each target are digitized and used in calculations describing the three-dimensional linear and angular motion of the anatomical segments. The digitized target coordinates contain significant broadband, high frequency noise which seriously compromises the usefulness of the data. An efficient recursive digital filter algorithm, developed to remove the noise from the data, is presented in this paper.
