Abstract
A plurality of depth maps corresponding to respective depth measurements determined over a respective plurality of time frames may be obtained. A plurality of skeleton representations respectively corresponding to the respective time frames may be obtained. Each skeleton representation may include joints associated with an observed entity. Local feature descriptors corresponding to the respective time frames may be determined, based on the depth maps and the joints associated with the skeleton representations. An activity recognition associated with the observed entity may be determined, based on the obtained skeleton representations and the determined local feature descriptors.
