A New Hip Fracture Risk Index Derived from FEA-Computed Proximal Femur Fracture Loads and Energies-to-Failure

no code implementations3 Oct 2022 Xuewei Cao, Joyce H Keyak, Sigurdur Sigurdsson, Chen Zhao, Weihua Zhou, Anqi Liu, Thomas Lang, Hong-Wen Deng, Vilmundur Gudnason, Qiuying Sha

The results showed that the average of the area under the receive operating characteristic curve (AUC) using PC1 was always higher than that using all FE parameters combined in the male subjects.

Deep-Learning-Based Audio-Visual Speech Enhancement in Presence of Lombard Effect

no code implementations29 May 2019 Daniel Michelsanti, Zheng-Hua Tan, Sigurdur Sigurdsson, Jesper Jensen

Regarding speech intelligibility, we find a general tendency of the benefit in training the systems with Lombard speech.

Unsupervised brain lesion segmentation from MRI using a convolutional autoencoder

no code implementations23 Nov 2018 Hans E. Atlason, Askell Love, Sigurdur Sigurdsson, Vilmundur Gudnason, Lotta M. Ellingsen

Lesions that appear hyperintense in both Fluid Attenuated Inversion Recovery (FLAIR) and T2-weighted magnetic resonance images (MRIs) of the human brain are common in the brains of the elderly population and may be caused by ischemia or demyelination.

Effects of Lombard Reflex on the Performance of Deep-Learning-Based Audio-Visual Speech Enhancement Systems

no code implementations15 Nov 2018 Daniel Michelsanti, Zheng-Hua Tan, Sigurdur Sigurdsson, Jesper Jensen

Humans tend to change their way of speaking when they are immersed in a noisy environment, a reflex known as Lombard effect.

On Training Targets and Objective Functions for Deep-Learning-Based Audio-Visual Speech Enhancement

no code implementations15 Nov 2018 Daniel Michelsanti, Zheng-Hua Tan, Sigurdur Sigurdsson, Jesper Jensen

Audio-visual speech enhancement (AV-SE) is the task of improving speech quality and intelligibility in a noisy environment using audio and visual information from a talker.
