A Segmentation and Analysis Method for MRI Data of the Human Vocal Tract
نویسندگان
چکیده
In this paper a method for three-dimensional modeling of the human vocal tract based on T1-weighted MRI data sets is introduced. This includes the reconstruction of the vocal tract shape and the computation of the vocal tract midline. Reconstruction of the vocal tract shape is realized by three-dimensional region growing within the vocal tract after teeth phantoms are matched into the MRI data set. The midline is obtained by using a modified 1d-Kohonen algorithm. Optimization and smoothing of the midline leads to computation of characteristic area functions. With those methods, human time expense could be reduced such that now a study of several subjects is possible.

Automated Segmentation of Upper Airways from MRI - Vocal Tract Geometry Extraction
A method for automatically extracting a triangulated surface mesh of the human vocal tract from 3D MRI data is proposed. The algorithm is based on a combination of anatomic landmarking, seeded region growing, and smoothing. More precisely, a mask is automatically created for removing unwanted details not associated with the vocal tract from the MRI voxel data. The mask then is applied to the or...

Vocal tract magnetic resonance imaging (MRI) has become one of the preferred imaging modalities for the analysis of human speech production. However, the raw image data must be segmented before further analysis can take place. This paper describes a hybrid approach to extract a 3D tongue model from 3D or 2D MRI scans of the vocal tract during speech, which combines unsupervised image segmentati...

متن کاملSegmentation and 3D reconstruction of the vocal tract from MR images – a comparative study
Speech production is an important human function involving a set of organs with specific morphological and dynamic aspects. The inter-speaker variability, the coarticulation or the nasality are some interesting aspects to improve a realistic 3D modeling of the vocal tract. For this, the understanding of the mechanism of speech production is crucial, as the current image data is not sufficient t...
