Abstract

This paper presents two different classifier fusion algorithms applied in the domain of Human Action Recognition from video A set of cameras observes a person performing an action from a predefined set For each camera view a 2D descriptor is computed and a posterior on the performed activity is obtained using a soft classifier These posteriors are combined using voting and a bayesian network to obtain a single belief measure to use for the final decision on the performed action Experiments are conducted with different low level frame descriptors on the IXMAS dataset, achieving results comparable to state of the art 3D proposals, but only performing 2D processing.
