The present work describes a new approach for the automatic tracking of the glottal area from high-speed digital images of the larynx. This approach involves three processes: Firstly, the frame with the maximal glottal opening is found automatically, by detecting the frame for which the sum of pixel intensities is minimum. Secondly, a segmentation algorithm based on active contours is used to d...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
