Giardina, G. (author), Hendriks, M.A.N. (author), Rots, J.G. (author)Excavation works in urban areas require a preliminary risk damage assessment. In historical cities, the prediction of building response to settlements is necessary to reduce the risk of damage of the architectural heritage. The current method used to predict the building damage due to ground deformations is the Limiting Tensile Strain Method ...conference paper 2009

Hendriks, R.L. (author), Völzke, R. (author), Kling, W.L. (author)High-voltage direct-current transmission based on voltage-sourced converters (VSC-HVDC) is an economic connection technology for large remote wind parks. Wind power plants that are connected through a VSC-HVDC link are subjected to the same technical connection requirements as conventional generators. The requirement that these installations...conference paper 2009

Ten Holt, G.A. (author), Arendsen, J. (author), De Ridder, H. (author), Van Doorn, A.J. (author), Reinders, M.J.T. (author), Hendriks, E.A. (author)Current automatic sign language recognition (ASLR) seldom uses perceptual knowledge about the recognition of sign language. Using such knowledge can improve ASLR because it can give an indication which elements or phases of a sign are important for its meaning. Also, the current generation of data-driven ASLR methods has shortcomings which may...conference paper 2009

Hendriks, E.A. (author), Reinders, M.J.T. (author)Methods commonly used for speech and sign language recognition often rely on outputs of Hidden Markov Models (HMM) or Dynamic TimeWarping (DTW) for classification, which aremerely factorized observation likelihoods. Instead, we propose to use Statistical DTW (SDTW) only for warping, while classifying the synchronized features with either of two...conference paper 2008

Lichtenauer, J.F. (author), Hendriks, E.A (author), Reinders, M.J.T. (author)To recognize speech, handwriting, or sign language, many hybrid approaches have been proposed that combine Dynamic Time Warping (DTW) or Hidden Markov Models (HMMs) with discriminative classifiers. However, all methods rely directly on the likelihood models of DTW/HMM. We hypothesize that time warping and classification should be separated...journal article 2008

(author)This work investigates knowledge driven segmentation of cardiac MR perfusion sequences. We build upon previous work on multi-band AAMs to integrate into the segmentation both spatial priors about myocardial shape as well as temporal priors about characteristic perfusion patterns. Different temporal and spatial features are developed without a...conference paper 2008

Hendriks, R.C. (author), Jensen, J. (author), Heusdens, R. (author)All discrete Fourier transform (DFT) domain-based speech enhancement gain functions rely on knowledge of the noise power spectral density (PSD). Since the noise PSD is unknown in advance, estimation from the noisy speech signal is necessary. An overestimation of the noise PSD will lead to a loss in speech quality, while an underestimation will...journal article 2008

Hendriks, R.C. (author)The interest in the field of speech enhancement emerges from the increased usage of digital speech processing applications like mobile telephony, digital hearing aids and human-machine communication systems in our daily life. The trend to make these applications mobile increases the variety of potential sources for quality degradation. Speech...doctoral thesis 2008

Erkelens, J.S. (author), Hendriks, R.C. (author), Heusdens, R. (author)This letter considers the estimation of speech signals contaminated by additive noise in the discrete Fourier transform (DFT) domain. Existing complex-DFT estimators assume independency of the real and imaginary parts of the speech DFT coefficients, although this is not in line with measurements. In this letter, we derive some general results on...journal article 2008

Labeling the pulmonary arterial tree in CT images for automatic quantification of pulmonary embolismPeters, R.J.M. (author), Marquering, H.A. (author), Dogan, H. (author), Hendriks, E.A. (author), De Roos, A. (author), Reiber, J.H.C. (author), Stoel, B.C. (author)Contrast-enhanced CT Angiography has become an accepted diagnostic tool for detecting Pulmonary Embolism (PE). The CT obstruction index proposed by Qanadli, which is based on the number of obstructed arterial segments, enables the quantification of PE severity. Because the required manual identification of twenty arterial segments is time...conference paper 2007
