Abstract
This paper is concerned with the extraction of spatio­
temporal patterns in video sequences with focus on trajec­
tories of gestural motions associated with American Sign
Language. An algorithm is described to extract the motion
trajectories of salient features such as human palms from
an image sequence. First, motion segmentation of the im­
age sequence is generated based on a multiscale segmen­
tation of the frames and attributed graph matching of re­
gions across frames. This produces region correspondences
and their affine transformations. Second, colors of the mov­
ing regions are used to determine skin regions. Third, the
head and palm regions are identified based on the shape and
