Abstract
A motion analysis system records a sequence of image frames of an event at a fast frame rate. A 2-D or 3-D still image depicting the kinetics of the multiple recorded, images is constructed by spatio-temporal visualization techniques. In the spatio-temporal (ST)-2-D technique, a path of pixels is defined showing travel of an object over time. The path of pixels of each image frame is represented in the ST-2-D image as a horizontal line of pixels. Each line in the vertical or horizontal direction is taken from one frame so that the sequence of lines represents the sequence of image frames of the event. In the ST-3-D visualization technique, a closed curve path of pixels is defined and represented in the ST-3-D image using 3-D graphical display techniques.
