Impulse illumination of a computer analyzed scene

A CCD TV camera and a light impulse source synchronized with the camera make it possible to track multiple objects in a frame (time) sharing regime while using a simple hard- & software which was developed for a real-time tracking of a single contrast object on a constant homogeneous background. We describe pilot experiments with tracking multiple objects marked by LED pulse light sources and discuss other possible applications of the frame sharing approach, e.g. in rehabilitation engineering as well as in computer vision.
