One of the key problems in a vision-based gesture recognition system is the extraction of spatial-temporal features of gesturing. In this paper anapproach of motion-based segmentation is proposed to realize this task. The directmethod cooperated with the robust M-estimator to estimate the affine parametersof gesturing motion is used, and based on the dominant motion model the gesturingregion is extracted, i.e., the dominant object. So the spatial-temporal features ofgestures can be extracted. Finally, the d…
