Recognition and tracking of articulatory organsin X-ray image sequences

Deformable organs of the human vocal tract are detected. An active contour is optimised by a dynamic programming algorithm, for which a new constraint is presented that introduces a priori knowledge on the shape of the expected boundary. The algorithm is able to detect convex and concave objects even when the image quality is poor.
