Since modern cameras provide sampling rates of several thousand frames per second, a high volume of data has to be considered for visual and objective analysis. A method for visualizing endoscopic high speed videos in three-dimensional cycle-based graphs combining and extending the approaches of phonovibrograms and electroglottographic wavegrams is presented. To build a phonovibrographic wavegram, individual cycles of a phonovibrogram are segmented, normalized in cycle duration, and concatenated over time. For analyzing purposes, the emerging three-dimensional scalar field is visualized with different rendering techniques providing information of different aspects of vocal fold kinematics. The phonovibrographic wavegram incorporates information about the glottal closure type, size, and location of the amplitudes, symmetry, periodicity, and phase information. The potential of the approach to visualize the characteristics of vocal fold vibration in a compact and intuitive way is demonstrated within two healthy and three pathologic subjects. The phonovibrographic wavegram allows a comprehensive analysis of vocal fold kinematics and reveals information that remains hidden with other visualization techniques.<\/jats:p>","DOI":"10.1121\/1.4774378","type":"journal-article","created":{"date-parts":[[2013,1,30]],"date-time":"2013-01-30T23:47:44Z","timestamp":1359589664000},"page":"1055-1064","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Phonovibrographic wavegrams: Visualizing vocal fold kinematics"],"prefix":"10.1121","volume":"133","author":[{"given":"Jakob","family":"Unger","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Applied Science Trier , Schneidershof, 54293 Trier, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Applied Science Trier , Schneidershof, 54293 Trier, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian T.","family":"Herbst","sequence":"additional","affiliation":[{"name":"Laboratory of Bio-Acoustics, Department of Cognitive Biology, University of Vienna , Althanstrasse 14, 1090 Wien, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.
