A Dependent Multilabel Classification Method Derived from the k-Nearest Neighbor Rule
EURASIP Journal on Advances in Signal Processing - Tập 2011 - Trang 1-14 - 2011
Zoulficar Younes (EURASIP Member), Fahed Abdallah, Thierry Denoeux, Hichem Snoussi
In multilabel classification, each instance in the training set is associated with a set of labels, and the task is to output a label set whose size is unknown a priori for each unseen instance. The most commonly used approach for multilabel classification is where a binary classifier is learned independently for each possible class. However, multilabeled data generally exhibit relationships betwe...... hiện toàn bộ
Three-Dimensional Facial Adaptation for MPEG-4 Talking Heads
EURASIP Journal on Advances in Signal Processing - Tập 2002 - Trang 1-16 - 2002
Nikos Grammalidis, Nikos Sarris, Fani Deligianni, Michael G. Strintzis
This paper studies a new method for three-dimensional (3D) facial model adaptation and its integration into a text-to-speech (TTS) system. The 3D facial adaptation requires a set of two orthogonal views of the user′s face with a number of feature points located on both views. Based on the correspondences of the feature points′ positions, a generic face model is deformed nonrigidly treating every f...... hiện toàn bộ
Fine-Grained Rate Shaping for Video Streaming over Wireless Networks
EURASIP Journal on Advances in Signal Processing - Tập 2004 - Trang 1-16 - 2004
Trista Pei-chun Chen, Tsuhan Chen
Video streaming over wireless networks faces challenges of time-varying packet loss rate and fluctuating bandwidth. In this paper, we focus on streaming precoded video that is both source and channel coded. Dynamic rate shaping has been proposed to "shape" the precompressed video to adapt to the fluctuating bandwidth. In our earlier work, rate shaping was extended to shape the channel coded precom...... hiện toàn bộ

Robust Adaptive Time Delay Estimation for Speaker Localization in Noisy and Reverberant Acoustic Environments
EURASIP Journal on Advances in Signal Processing - Tập 2003 - Trang 1-15 - 2003
Simon Doclo, Marc Moonen
Two adaptive algorithms are presented for robust time delay estimation (TDE) in acoustic environments with a large amount of background noise and reverberation. Recently, an adaptive eigenvalue decomposition (EVD) algorithm has been developed for TDE in highly reverberant acoustic environments. In this paper, we extend the adaptive EVD algorithm to noisy and reverberant acoustic environments, by d...... hiện toàn bộ
On the inclusion of prime factors to calculate the theoretical lower bounds in multiplierless single constant multiplications
EURASIP Journal on Advances in Signal Processing - Tập 2014 - Trang 1-9 - 2014
David E Troncoso Romero, Uwe Meyer-Baese, Gordana Jovanovic Dolecek
This paper presents an extension to the theoretical lower bounds for the number of adders and for the adder depth in multiplierless single constant multiplications (SCM). It is shown that the number of prime factors of the constants is key information to extend the current lower bounds in certain cases that have not yet been exposed. Additionally, the hidden theoretical lower bound for the number ...... hiện toàn bộ
Interference Management Schemes for the Shared Relay Concept
EURASIP Journal on Advances in Signal Processing - Tập 2011 - Trang 1-14 - 2010
Ali Y. Panah, Kien T. Truong, Steven W. Peters, Robert W. Heath
Sharing a multiantenna relay among several sectors is a simple and cost-effective way to achieving much of the gains of local interference mitigation in cellular networks. Next generation wireless systems, such as ones based on the Third Generation Partnership Projects Long-Term Evolution Advanced, will employ universal frequency reuse to simplify network deployment. This strategy is anticipated t...... hiện toàn bộ

Efficient Alternatives to the Ephraim and Malah Suppression Rule for Audio Signal Enhancement
EURASIP Journal on Advances in Signal Processing - Tập 2003 - Trang 1-9 - 2003
Patrick J. Wolfe, Simon J. Godsill
Audio signal enhancement often involves the application of a time-varying filter, or suppression rule, to the frequency-domain transform of a corrupted signal. Here we address suppression rules derived under a Gaussian model and interpret them as spectral estimators in a Bayesian statistical framework. With regard to the optimal spectral amplitude estimator of Ephraim and Malah, we show that under...... hiện toàn bộ
Using Invariant Image Features for Synchronization in Spread Spectrum Image Watermarking
EURASIP Journal on Advances in Signal Processing - Tập 2002 - Trang 1-8 - 2002
Ebroul Izquierdo
A watermarking scheme is presented in which the characteristics of both spatial and frequency techniques are combined to achieve robustness against image processing and geometric transformations. The proposed approach consists of three basic steps: estimation of the just noticeable image distortion, watermark embedding by adaptive spreading of the watermark signal in the frequency domain, and extr...... hiện toàn bộ
