Proceedings ArticleDOI

Quantile based noise estimation for spectral subtraction and Wiener filtering

TL;DR: This paper restricts its considerations to the case where only a single microphone recording of the noisy signal is available and proposes a method based on temporal quantiles in the power spectral domain, which is compared with pause detection and recursive averaging.
Journal ArticleDOI

Is multidetector CT-based bone mineral density and quantitative bone microstructure assessment at the spine still feasible using ultra-low tube current and sparse sampling?

TL;DR: In ultra-low-dose scans, BMD and microstructure parameters were able to differentiate subjects with and without vertebral fractures, suggesting osteoporosis diagnosis is feasible, however, absolute values differed from original values.
Journal ArticleDOI

Motion artifact recognition and quantification in coronary CT angiography using convolutional neural networks

TL;DR: First machine‐learning‐based measures for coronary motion artifact recognition and quantification and higher robustness regarding variations in background intensities compared to state of the art handcrafted measures are proposed.
Journal ArticleDOI

Feasibility of [18F]-2-Fluoro-A85380-PET Imaging of Human Vascular Nicotinic Acetylcholine Receptors In Vivo

TL;DR: Approaches to evaluate [(18)F]-2-Fluoro-A85380 for in vivo imaging of arterial nicotinic acetylcholine receptors (nAChRs) in humans can provide specific information on the nAChR distribution in human arteries and might provide insights into the pathogenic role of nA ChRs in the human vasculature.
Proceedings ArticleDOI

Acoustic synthesis of training data for speech recognition in living room environments

TL;DR: This work compares the performance of a speech recognizer trained on recorded speech in the target domain with a system trained on suitably transformed clean speech, based on two channel recordings with a close talk and a distant microphone.
