Automatic high-speed video glottis segmentation using salient regions and 3D geodesic active contours
Verbal communication plays an important role in our economy. Laryngeal high-speed videos have emerged as a state of the art method to investigate vocal fold vibrations in the context of voice disorders affecting verbal communication. Segmentation of the glottis from these videos is required to analyze vocal fold vibrations. The vast amount of data produced makes manual segmentation impossible i...
متن کاملAutomatic Glottis Segmentation from Laryngeal High-Speed Videos Using 3D Active Contours
Laryngeal high-speed videos are a state of the art method to investigate vocal fold vibration but the vast amount of data produced prevents it from being used in clinical applications. Segmentation of the glottal gap is important for excluding irrelevant data from video frames for subsequent analysis. We present a novel, fully automatic segmentation method involving rigid motion compensation, s...
متن کاملA Fully Automatic Cerebellum Segmentation Method using an Active Contour Model with Shape Prior
Introduction 3D visualization and functional analysis of human brain require segmentation of cerebrum and cerebellum from brain magnetic resonance (MR) images. Many methods for brain extraction were developed, but segmentation of the cerebellum from brain region is still difficult. This difficulty mainly comes from partial volume effect that makes the task of delineating the boundary challengin...
متن کاملReal-Time Active Shape Models for Segmentation of 3D Cardiac Ultrasound
We present a fully automatic real-time algorithm for robust and accurate left ventricular segmentation in three-dimensional (3D) cardiac ultrasound. Segmentation is performed in a sequential state estimation fashion using an extended Kalman filter to recursively predict and update the parameters of a 3D Active Shape Model (ASM) in real-time. The ASM was trained by tracing the left ventricle in ...
متن کاملAnalysis of Voice - Onset Using Active Rays andHidden
In this paper we describe an approach for an automatic evaluation system for laryngoscopical image sequences. We describe how glottis segmentation in high speed camera sequences can be done by using active rays. We show that active ray contour segmentation provides a good base for useful feature calculation. Afterwards we show how hidden Markov models (HMMs) can serve for a statistical evaluati...
