Abstract
The analysis of human activities is one of the most interesting and important open issues for the automated video
surveillance community. In order to understand the behaviors of humans, a higher level of understanding is required, which is
generally referred to as activity recognition. While traditional approaches rely on 2D data like images or videos, the development of
low-cost depth sensors created new opportunities to advance the field. In this paper, a system to recognize human activities using 3D
skeleton joints recovered from 3D depth data of RGB-D cameras is proposed. A low dimensional descriptor is constructed for activity
recognition based on skeleton joints. The proposed system focuses on recognizing human activities not human actions. Human activities
take place over different time scales and consist of a sequence of sub-activities (referred to as actions). The proposed system recognizes
learned activities via trained Hidden Markov Models (HMMs). Experimental results on two human activity recognition benchmarks
show that the proposed recognition system outperforms various state-of-the-art skeleton-based human activity recognition techniques.
