Estimation of glottal area function using stereo-endoscopic high-speed digital imaging

In this paper, a novel stereo-endoscopic high-speed digital imaging system and a method to estimate the glottal area function are proposed. Glottal length, width, and area of one female participant were estimated in three different fundamental frequencies (F0s).

Analysis of the Voice Source in Different Phonation Types: Simultaneous High-Speed Imaging of the Vocal Fold Vibration and Glottal Inverse Filtering

Glottal flow waveforms estimated by inverse filtering acoustic speech pressure signals were compared to glottal area functions obtained by digital high-speed imaging of the vocal fold vibration. Speech data consisted of breathy, normal and pressed phonations produced by two male and one female subjects. The results yield both qualitative and quantitative information about the relationship betwe...

A Comparison of Patients Absorption Doses with Bone Deformity Due to the EOS Imaging and Digital Radiology

  Background: This study has aimed to measure the patient dose in entire spine radiography by EOS system in comparison with the digital radiography. Methods: EOS stereo-radiography was used for frontal and lateral view spine imaging in 41 patients in a prospective analytical study. A calibrated dose area product (DAP) meter was used for calibration of the DAP in EOS system. The accuracy and pr...

Automatic glottal tracking from high-speed digital images using a continuous normalized cross correlation

The present work describes a new approach for the automatic tracking of the glottal area from high-speed digital images of the larynx. This approach involves three processes: Firstly, the frame with the maximal glottal opening is found automatically, by detecting the frame for which the sum of pixel intensities is minimum. Secondly, a segmentation algorithm based on active contours is used to d...
