Quantification of Respiratory Laryngeal Morphometry: Comparison of Laryngeal Lumen Angle Estimate Methods

Laryngeal lumen angles can be used to measure respiratory laryngeal morphometry. However, image-correction algorithms are necessary to correct images and quantify morphometric estimate error caused by camera lens distortion and lens-to-object perspective. Findings provide a platform for future research on quantifying laryngeal morphometry, especially for individuals with laryngeal breathing disorders.
