Anac, C. (author), Esposito, R. (author), Copuroglu, O. (author), Schlangen, H.E.J.G. (author), Hendriks, M.A.N. (author)This paper outlines a project (namely PAT-ASR) which entails the development of a multi scale material performance assessment model on simulation of alkali silica reaction deployment and its effects on concrete durability. Performance models require a multi scale approach from micro (namely reaction chemistry) to macro level studies (namely...conference paper 2012

Taal, C.H. (author), Hendriks, R.C. (author), Heusdens, R. (author), Jensen, J. (author)Existing objective speech-intelligibility measures are suitable for several types of degradation, however, it turns out that they are less appropriate in cases where noisy speech is processed by a time-frequency weighting. To this end, an extensive evaluation is presented of objective measure for intelligibility prediction of noisy speech...journal article 2011

Van der Maaten, L.J.P. (author), Hendriks, E.A. (author)In this paper, we investigate to what extent modern computer vision and machine learning techniques can assist social psychology research by automatically recognizing facial expressions. To this end, we develop a system that automatically recognizes the action units defined in the facial action coding system (FACS). The system uses a...journal article 2011

Snelder, M. (author), Egeter, B. (author), Hendriks, T. (author), Immers, L.H. (author)P+R-plus is a new layer of P+R (Park and Ride) on top of existing P+R facilities at many public transport stops. Someone who parks his car at a P+R-plus location is guaranteed that he can reach all important locations within a metropolitan region with a maximum of one transfer and with metro quality (reliable and highly frequent). This implies...conference paper 2011

Mouthaan, M.M. (author), Van den Broek, S.P. (author), Hendriks, E.A. (author), Schwering, P.B.W. (author)We evaluate the performance of different key-point detectors and region descriptors when used for automatic classification of small sea targets in infrared video. In our earlier research performed on this subject as well as in other literature, many different region descriptors have been proposed. However, it is unclear which methods are most...journal article 2011

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

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

(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 der Maaten, L.J.P. (author), Hendriks, E.A. (author)The paper presents an extension of active appearance models (AAMs) that is better capable of dealing with the large variation in face appearance that is encountered in large multi-person face data sets. Instead of the traditional PCA-based texture model, our extended AAM employs a mixture of probabilistic PCA to describe texture variation,...conference paper 2010

Zheng, S. (author), Hendriks, E.A. (author), Lei, B. (author), Hao, W. (author)Under the support vector machine framework, the support value analysis-based image fusion has been studied, where the salient features of the original images are represented by their support values. The support value transform (SVT)-based image fusion approach have demonstrated some advantages over the existing methods in multisource image...conference paper 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

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
