Voice is a critical tool for communication, and diagnosing voice disorders poses significant challenges, particularly when using high-speed video (HSV) endoscopy. The primary difficulty with HSV lies in the need for clinical experts to manually analyze and interpret large volumes of HSV frames. To address these challenges, kymography has been introduced as an effective clinical decision-support tool.

- The study investigates glottal dynamics in vocal fold disorders (leukoplakia, laryngitis, papilloma) using visualization technologies like PVG and GVG to improve diagnosis and classification.
- The research employs high-speed video endoscopy and various imaging techniques to analyze the vibratory patterns of affected vocal folds, revealing distinct differences in their behavior.
- Ultimately, the findings suggest that these advanced visualization methods provide crucial insights into vocal fold dynamics, supporting better understanding and assessment of voice disorders compared to traditional methods.

Laryngeal high-speed video endoscopy is performed to examine the cycles of vocal fold vibrations in detail and to diagnose voice abnormalities. One of the recent image processing techniques for visualizing vocal fold vibration is optical flow-based playbacks, which include optical flow kymograms (OFKG) for local dynamics, optical flow glottovibrogram (OFGVG) and glottal optical flow waveforms (GOFW) for global dynamics. In recent times, various optical flow computing algorithms have been developed.
