Segmentation of X-ray Image Sequences Showing the Vocal Tract

The tongue, the lips, the palate, and the throat are tracked in X-ray images showing the side view of the vocal tract. This is performed by using specialized histogram normalization techniques and a new tracking method that is robust against occlusion, noise, and spontaneous, non-linear deformations of objects. Although the segmentation procedure is optimized for the X-ray images of the vocal tract, the underlying tracking method can easily be used in other applications.
