Robust contour tracking in ultrasound tongue image sequences.

Robust contour tracking in ultrasound tongue image sequences. Clin Linguist Phon. 2016 Jan 20;:1-15 Authors: Xu K, Yang Y, Stone M, Jaumard-Hakoun A, Leboullenger C, Dreyfus G, Roussel P, Denby B Abstract 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. To cope with missing segments caused by noise, or by the tongue midsagittal surface being parallel to the direction of ultrasound wave propagation, active contours with a contour-similarity constraint are introduced, which can be used to provide 'prior' shape information. Also, in order to address accumulation of tracking errors over long sequences, we present an automatic re-initialization technique, based on the complex wavelet image similarity index. Experiments on synthetic data and on real 60 frame per second (fps) data from different subjects demonstrate that the proposed method gives good contour tracking for ultrasound image sequences even over durations of minutes, which can be useful in applications such as speech recognition where very long sequences must be analyzed in their entirety.

Publication date: March 2020Source: Materials Science and Engineering: B, Volume 253Author(s): Bingchi Luo, Yudan He, Kai Li, Lei jin, Bo Li, Jiangshan LuoAbstractThe beryllium (Be) films were prepared by vacuum evaporation with ultrasound on the glass slide substrates. The Be coating mainly consists of α-Be phase independent of ultrasonic vibration, while the texture and crystallinity are affected by ultrasonic vibration. With the increasing of ultrasonic power, the surface displays polygonal grains, but the grain size decreases from 130 nm to 60 nm. The cross section views show a transition from regular columna...

This study was dedicated to the functionalisation of flaxseed proteins by ultrasonication to produce coatings enriched with flaxseed proteins and raspberry phytochemicals. High frequency (850 kHz) ultrasound (US) was used for the texturization of flaxseed proteins at 50 °C temperature. The functional properties of proteins (emulsifying, foaming, and gelling) significantly (p

This study aims to investigate whether HIF-1/BNIP3-mediated mitochondrial autophagy is involved in the restoration of sevoflurane postconditioning cardioprotection in diabetic state. Ischemia/reperfusion (I/R) model was established by ligating the anterior descending coronary artery and sevoflurane was administered at the first 15 min of reperfusion. Myocardial infarct size, mitochondrial ultrastructure and autophagosome, ATP content, mitochondrial membrane potential, ROS production, HIF-1α, BNIP3, LC3B-II, Beclin-1, P62, LAMP2 protein expression were detected 2 h after reperfusion, and cardiac function was evaluated...

AbstractIn conventional techniques of anatomic hepatectomy, boundaries of hepatic segments are identified by injection of blue dye (indigo carmine) into the corresponding portal branch under ultrasound guidance [1]. Recently, fluorescence imaging following the injection of indocyanine green (ICG) solution into the portal branch has been used for clearer visualization of hepatic segments [2 –4].
