(HSV). The method employs a pair of active contours (snakes), which deform within a series of kymographic images derived from the HSV data. By following a set of deformation rules, this pair of active contours converges to the desired boundaries of the glottis. The proposed method was tested on a dataset of 98 HSV samples, of which 96 were successfully segmented. The new method substantially ou...

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, ...

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 ...

been facilitated by the introduction of en− doscopic imaging at high resolution. Re− cently, minimal changes at the squamo− columnar (SC) junction have attracted clinical interest; these are defined by en− doscopists as white−colored changes to the esophageal mucosa near the SC junc− tion. This finding is commonly accepted for inclusion in a modified LA classifica− tion “grade M (minimal change...

Colorectal endoscopy is important for the early detection and treatment of colorectal cancer and is used worldwide. A computer-aided diagnosis (CAD) system that provides an objective measure to endoscopists during colorectal endoscopic examinations would be of great value. In this study, we describe a newly developed CAD system that provides real-time objective measures. Our system captures the...

OBJECTIVES To present a method called Fourier image (FI) for analyzing high-speed videoendoscopy recordings. These false-color images visualize functional vocal fold properties and allow the quantification of phase relations. Furthermore, reference data for phase asymmetries in normophonic speakers as assessed with this method are provided. STUDY DESIGN Prospective study. METHODS Phase rela...

UNLABELLED Patients with dysphagia have impairments in many aspects, and an interdisciplinary approach is fundamental to define diagnosis and treatment. A joint approach in the clinical and videoendoscopy evaluation is paramount. AIM To study the correlation between the clinical assessment (ACD) and the videoendoscopic (VED) assessment of swallowing by classifying the degree of severity and t...
