Mutually reinforcing motion-pose framework for pose invariant action recognition. International Journal of Biometrics, 11(2), 113-147. doi:10.1504/IJBM.2019.099014 | Journal: | International Journal of Biometrics | Abstract: | Action recognition from videos has many potential applications. However, there are many unresolved challenges, such as pose-invariant recognition, robustness to occlusion and others. In this paper, we propose to combine motion of body parts and pose hypothesis generation validated with specific canonical poses observed in a novel mutually reinforcing framework to achieve pose-invariant action recognition. To capture the temporal dynamics of an action, we introduce temporal stick features computed using the stick poses obtained. The combination of pose-invariant kinematic features from motion, pose hypothesis and temporal stick features are used for action recognition, thus forming a mutually reinforcing framework that repeats until the action recognition result converges. The proposed mutual reinforcement framework is capable of handling changes in posture of the person, occlusion and partial view-invariance. We perform experiments on several benchmark datasets which showed the performance of the proposed algorithm and its ability to handle pose variation and occlusion. | URI: | https://hdl.handle.net/10356/142072 | ISSN: | 1755-8301 | DOI: | 10.1504/IJBM.2019.099014 | Schools: | School of Electrical and Electronic Engineering | Research Centres: | Institute for Media Innovation (IMI) Research Techno Plaza |
