A region based approach for human body motion analysis

Abstract

Human body motion analysis can be roughly divided into three phases. In the first phase, moving body parts are separated from the background. In the second phase, these body parts are then labelled. In the third phase, the motion verbs are assigned to the movement. An earlier paper by the authors described a novel technique for segmenting the moving body parts from the background. In this paper, techniques developed for the second phase of the analysis are discussed. The notion of antiparallel lines is employed to abstract the regions into a higher level primitive which enables one to define and develop operations such as concatenation and deletion. A simple heuristic model is then used to map the detected regions into human body parts. Results of which are very encouraging. Future research in the proposed approach is warranted.
