Direct, Near Real Time Animation of a 3D Tongue Model Using Non-Invasive Ultrasound Images

Shicheng Chen, Yifeng Zheng, Chengrui Wu, Guorui Sheng, Pierre Roussel, Bruce Denby

ICASSP 2018accepted

A new technique for representing speech articulation with an ultrasound-driven finite element model of the tongue is presented. By using a snake contour extraction algorithm with anatomically motivated constraints and a common coordinate system between the ultrasound and the tongue model, it is poss…

Toward Secure Image Denoising: A Machine Learning Based Realization

Yifeng Zheng, Cong Wang, Jiantao Zhou

ICASSP 2018accepted

Image denoising via machine learning techniques, particularly neural networks, has been shown to achieve state-of-the-art performance. However, in practice security and privacy issues undesirably arise in applying a trained machine learning model to image denoising. In this paper, we propose a syste…
