Paper Abstract

For human motion analysis, the spatio-temporal resolution of cinematographic registrations of body marker positions is still higher than the results of the best opto electronic systems available for this purpose today. So far, the need for manual digitization of several thousand marker positions per tested person has made this method unpractical for regular applications. An interactive and largely automated system for marker recognition and tracking from 16 mm film images based on progress in digital image processing has been developed and tested. Projected pictures are digitized with a high-resolution CCD-camera (1320x1035 pixel), processed, analyzed and serially evaluated with an interactive image analysis system SIGNUM IS200.
