Laryngeal High-Speed Videoendoscopy: Sensitivity of Objective Parameters towards Recording Frame Rate
The current use of laryngeal high-speed videoendoscopy in clinic settings involves subjective visual assessment of vocal fold vibratory characteristics. However, objective quantification of vocal fold vibrations for evidence-based diagnosis and therapy is desired, and objective parameters assessing laryngeal dynamics have therefore been suggested. This study investigated the sensitivity of the ...
متن کاملClinical implementation of laryngeal high-speed videoendoscopy: challenges and evolution.
High-speed videoendoscopy (HSV) captures the true intracycle vibratory behavior of the vocal folds, which allows for overcoming the limitations of videostroboscopy for more accurate objective quantification methods. However, the commercial HSV systems have not gained widespread clinical adoption because of remaining technical and methodological limitations and an associated lack of information ...
متن کاملVector Machine Based Decision Tree to Classify Voice Pathologies Using High - Speed Videoendoscopy
Objective/Hypothesis: Little research has explored the potential of computer assisted decision making applied to high-speed videoendoscopy. In this paper, we propose a computer based method for differentiating normal and pathological larynges on the basis of HSV. Methods: HSV recordings were collected from 101 patients with normal larynges, leukoplakia, nodules or polyps. After pre-processing, ...
متن کاملFast FFT-based motion compensation for laryngeal high-speed videoendoscopy
(HSV) are compared. Two of them are based on tracking the maximum of the cross-correlation function of two images; two are based on minimization of the L 2 –norm and L 2-like distance between two images ; and the other two make use of the peak present in the cross-power FFT-based spectrum of two images. All six methods are applied to compensate the motion, at the sub-pixel level, of the endosco...
متن کاملUsual to Particular Phonatory Situations Studied with High-speed Videoendoscopy
Current high-speed videoendoscopy (HSV) make it possible to obtain 4000 images of the larynx per second. By this process, the analysis of the vocal folds can provide significant information. This is also possible to estimate the area of the glottis. All this information is useful for the study of the various phonatory modes, but also for glottal flow estimation which allows the improvement of o...
