Felix, F. (author), Fraaij, A.L.A. (author), Hendriks, Ch.F. (author)In this paper the advantages en disadvantages of three different Stabilisation/Solidification-treatments are discussed. The first treatment, cement based SIS-treatment, is based on the hydration reaction of cement by which heavy metals chemically and or physically are bound. Cement based SIS-treatment is more critical with regard to the used...journal article

Lei, B.J. (author), Hendriks, E.A. (author)We propose a real-time multi-step view reconstruction algorithm and we tune its implementation to a virtual teleconference application. Theoretical motivations and practical implementation issues of the algorithm are detailed. The proposed algorithm can be used to reconstruct novel views at arbitrary poses (position and orientation) in a way...journal article 2002

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

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

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

Hendriks, R.C. (author), Heusdens, R. (author), Kjems, U. (author), Jensen, J. (author)In this letter we present discrete Fourier transform (DFT) domain minimum mean-squared error (MMSE) estimators for multichannel noise reduction. The estimators are derived assuming that the clean speech magnitude DFT coefficients are generalized-Gamma distributed. We show that for Gaussian distributed noise DFT coefficients, the optimal...journal article 2009

Heusdens, R. (author), Hendriks, R.C. (author), Jensen, J. (author), Kjems, U. (author)Although most noise reduction algorithms are critically dependent on the noise power spectral density (PSD), most procedures for noise PSD estimation fail to obtain good estimates in nonstationary noise conditions. Recently, a DFT-subspace-based method was proposed which improves noise PSD estimation under these conditions. However, this...journal article 2009

(author)The analysis of multi-timepoint whole-body small animal CT data is greatly complicated by the varying posture of the subject at different timepoints. Due to these variations, correctly relating and comparing corresponding regions of interest is challenging. In addition, occlusion may prevent effective visualization of these regions of interest....journal article 2010

Van Bijleveld, C. (author), Hendriks, R.C. (author), Heusdens, R. (author), Taal, C.H. (author)A pair of properly functioning ears is of great importance for various common daily tasks. While the perception of speech is perhaps one of the most obvious examples, being notified by certain sounds like (fire-) alarms or traffic sounds can even be lifesaving. Therefore it is not surprising that hearing impairment may have a strong (social)...journal article 2010

Xu, Y.C. (author), Lei, B. (author), Hendriks, E.A. (author)This paper studies how to improve the field of view (FOV) coverage of a camera network. We focus on a special but practical scenario where the cameras are randomly scattered in a wide area and each camera may adjust its orientation but cannot move in any direction. We propose a particle swarm optimization (PSO) algorithm which can efficiently...journal article 2011
