Tracking Articulators in X-ray Movies of the Vocal Tract
Tongue, lips, palate, and throat are tracked in X-ray films showing the side-view of the vocal tract. Specialized histogram normalization techniques and a new tracking method that is robust against occlusion, noise, and spontaneous, non-linear deformations of objects are used. Although the segmentation procedure is optimized for the X-ray images of the vocal tract, the underlying tracking method can be used in other applications.
