Is Speckle Tracking Feasible for Ultrasound Tongue Images?

Using a Biomechanical Model for Tongue Tracking in Ultrasound Images

We propose in this paper a new method for tongue tracking in ultrasound images which is based on a biomechanical model of the tongue. The deformation is guided both by points tracked at the surface of the tongue and by inner points of the tongue. Possible uncertainties on the tracked points are handled by this algorithm. Experiments prove that the method is efficient even in case of abrupt move...

Robust tongue tracking in ultrasound images: a multi-hypothesis approach

Ultrasound (US) imaging is an excellent means of observing tongue motion during speech. Tracking the tongue contour in US video is required for analysis of this motion, but most currently available techniques suffer from either a lack of temporal consistency or a lack of robustness to difficult conditions such as a rapidly deforming tongue or momentarily poor image quality. This paper proposes ...

Ultrasound Speckle Tracking For Strain Estimation

This paper presents an alternative to Elastography by speckle tracking ultrasonic frames quantifying both motion and strain. We combine two similarity measures for varying echographic content including displacement processing, with interframe and trajectory performance measured on extensive synthetic and in vitro data.

Speckle Reducing Filtering for Ultrasound images

Speckle noise is undesired result which appear during the image formation process in that is most typically known to occur in the coherent imaging systems for example ultrasound imaging, sonar, lasers, synthetic aperture radar and many more. So the presence of speckle in ultrasound imaging system results in decrease in quality of image and it become quite difficult for human to diagnose and int...
