Robust contour tracking in ultrasound tongue image sequences
TLDR
A new contour-tracking algorithm is presented for ultrasound tongue image sequences, which can follow the motion of tongue contours over long durations with good robustness and can be useful in applications such as speech recognition where very long sequences must be analyzed in their entirety.
