Abstract
Human motions generate characteristic spatiotem-
poral patterns. We have developed a set of techniques
for analyzing the patterns generated by people walk-
ing across the eld of view. After change detection,
the XYT pattern can be t with a smooth spatiotem-
poral surface. This surface is approximately periodic,
re ecting the periodicity of the gait. The surface can
be expressed as a combination of a standard parame-
terized surface { the canonical walk { and a deviation
surface that is speci c to the individual walk.
