WMicaD: A New Digital Watermarking Technique Using Independent Component Analysis
EURASIP Journal on Advances in Signal Processing - Tập 2008 - Trang 1-9 - 2007
Thang Viet Nguyen, Jagdish Chandra Patra, Pramod Kumar Meher
This paper proposes a new two-mark watermarking scheme that is based on the independent component analysis (ICA) technique. The first watermark is used for ownership verification while the second one is used as the copy ID of the image. Using a small-sized support image, the extraction is carried out on size-reduced level, bringing computational advantage to our method. The new method, undergoing ...... hiện toàn bộ
Efficient sliding spotlight SAR raw signal simulation of extended scenes
EURASIP Journal on Advances in Signal Processing - Tập 2011 - Trang 1-7 - 2011
Wei Xu, Pingping Huang, Yunkai Deng
Sliding spotlight mode is a novel synthetic aperture radar (SAR) imaging scheme with an achieved azimuth resolution better than stripmap mode and ground coverage larger than spotlight configuration. However, its raw signal simulation of extended scenes may not be efficiently implemented in the two-dimensional (2D) Fourier transformed domain. This article presents a novel sliding spotlight raw sign...... hiện toàn bộ
Robust Real-Time Tracking for Visual Surveillance
EURASIP Journal on Advances in Signal Processing - Tập 2007 Số 1 - Trang 1-23 - 2006
Thirde, David, Borg, Mark, Aguilera, Josep, Wildenauer, Horst, Ferryman, James, Kampel, Martin
This paper describes a real-time multi-camera surveillance system that can be applied to a range of application domains. This integrated system is designed to observe crowded scenes and has mechanisms to improve tracking of objects that are in close proximity. The four component modules described in this paper are (i) motion detection using a layered background model, (ii) object tracking based on...... hiện toàn bộ
Performance evaluation of space-time-frequency spreading for MIMO OFDM-CDMA systems
EURASIP Journal on Advances in Signal Processing - Tập 2011 - Trang 1-13 - 2011
Haysam Dahman, Yousef Shayan
In this article, we propose a multiple-input-multiple-output, orthogonal frequency division multiplexing, code-division multiple-access (MIMO OFDM-CDMA) scheme. The main objective is to provide extra flexibility in user multiplexing and data rate adaptation, that offer higher system throughput and better diversity gains. This is done by spreading on all the signal domains; i.e, space-time frequenc...... hiện toàn bộ
Multichannel SAR Interferometry via Classical and Bayesian Estimation Techniques
EURASIP Journal on Advances in Signal Processing - Tập 2005 - Trang 1-14 - 2005
Alessandra Budillon, Giancarlo Ferraiuolo, Vito Pascazio, Gilda Schirinzi
Some multichannel synthetic aperture radar interferometric configurations are analyzed. Both across-track and along-track interferometric systems, allowing to recover the height profile of the ground or the moving target radial velocities, respectively, are considered. The joint use of multichannel configurations, which can be either multifrequency or multi-baseline, and of classical or Bayesian s...... hiện toàn bộ
Vital sign sensing method based on EMD in terahertz band
EURASIP Journal on Advances in Signal Processing - Tập 2014 - Trang 1-8 - 2014
Zhengwu Xu, Tong Liu
Non-contact respiration and heartbeat rates detection could be applied to find survivors trapped in the disaster or the remote monitoring of the respiration and heartbeat of a patient. This study presents an improved algorithm that extracts the respiration and heartbeat rates of humans by utilizing the terahertz radar, which further lessens the effects of noise, suppresses the cross-term, and enha...... hiện toàn bộ
A Self-Adaptive Approach for the Detection and Correction of Stripes in the Sinogram: Suppression of Ring Artifacts in CT Imaging
EURASIP Journal on Advances in Signal Processing - Tập 2011 - Trang 1-13 - 2010
A. N. M. Ashrafuzzaman, Soo Yeol Lee, Md. Kamrul Hasan
The digital X-ray detectors often generate stripe artifact in the sinogram which in turn creates ring artifact in the reconstructed micro-Computed Tomography ( -CT), C-Arm CT, and most recent dental CT images. Such ring artifacts not only obscure image details in the regions of interest but also mask the whole image with some artif...... hiện toàn bộ
An improved monarch butterfly spectrum allocation algorithm for multi-source data stream in complex electromagnetic environment
EURASIP Journal on Advances in Signal Processing -
Yuchao Liu, Chenggang Cao, Yu Han
AbstractIn the era of the Internet of Everything, various wireless devices and sensors use spectrum, which is a precious and non-renewable resource, to communication. Due to the characteristics of massive, heterogeneous, and multi-source, the generated multi-source data stream brings difficulties to spectrum cognition. As a result, unreasonable spectrum allocation ...... hiện toàn bộ
Simple Statistical Analysis of the Impact of Some Nonidealities in Downstream VDSL with Linear Precoding
EURASIP Journal on Advances in Signal Processing - Tập 2010 Số 1 - 2010

Single-Frame Image Super-resolution through Contourlet Learning
EURASIP Journal on Advances in Signal Processing - Tập 2006 - Trang 1-5 - 2006
CV Jiji, Subhasis Chaudhuri
We propose a learning-based, single-image super-resolution reconstruction technique using the contourlet transform, which is capable of capturing the smoothness along contours making use of directional decompositions. The contourlet coefficients at finer scales of the unknown high-resolution image are learned locally from a set of high-resolution training images, the inverse contourlet transform o...... hiện toàn bộ
