Description

This paper describes a system which automatically digitizes human movement without using reference marks on the body. For this system, a MathLink program "MovieDigitizer" which one of the author wrote was used. MovieDigitizer which runs on the Macintosh reads QuickTikme files and communicates the graphical information with Mathematica using MathLink. The automatic digitizing is based on model matching. A two-dimensional human body shape model and a captured human body image are superimposed and parameters such as human body positions, angles and displacements are calculated to minimize the difference of the two images. The MovieDigitizer in combination with Mathematica forms a powerful and flexible digitizing system.
