Multi-hypothesis tracking of the tongue surface in ultrasound video recordings of normal and impaired speech.
Medical Image Analysis(2018)
摘要
•A new method based particle filtering robustly tracks the tongue in US images.•The method does not require a large or very diverse training set.•The method is accurate in both normal and impaired speech US data.•It yields low distance error and high shape correlation compared to ground truth.•Its accuracy is an improvement over Edgetrak, Autotrace and TongueTrack.
