CONF Lopez-Mendez_ICIP_2014/IDIAP Automated Bobbing and Phase Analysis to Measure Walking Entrainment Lopez-Mendez, Adolfo Westling, C. E. I Emonet, Remi Easteal, M. Lavia, L. Witchel, H. J. Odobez, Jean-Marc bobbing estimation entrainment to music gait tracking IEEE International Conference on Image Processing (ICIP), Paris 2014 In this paper, we investigate the influence of music on human walking behaviors in a public setting monitored by surveillance cameras. To this end, we propose a novel algorithm to characterize the frequency and phase of the walk. It relies on a human-by-detection tracking framework, along with a robust fitting of the human head bobbing motion. Preliminary experiments conducted on more than 100 tracks show that an accuracy greater than 85% for foot strike estimation can be achieved, suggesting that large scale analysis is at reach for finer music/walking behavior relationship studies.
