On signals compression by EMD
Codage des signaux par EMD
TypeArticles dans des revues avec comité de lecture
In this letter a new signals coding framework based on the Empirical Mode Decomposition (EMD) is introduced. The EMD breaks down any signal into a reduced number of oscillating components called Intrinsic Modes Decomposition (IMFs). Based on IMF properties, different coding strategies are presented. No assumptions concerning the linearity or the stationarity are made about the signal to be coded. Results obtained on ECG signals are presented and compared to those of wavelets coding.

DIOP, El Hadji; ALEXANDRE, Radjesvarane; BOUDRAA, Abdel-Ouahab (IEEE, 2010)The empirical mode decomposition is a powerful tool for signal processing. Because of its original algorithmic, recent works have contributed to its theoretical framework. Following these works, some mathematical contributions ...
BAY AHMED, Hadj Ahmed; KOMATY, Ali; DARE, Delphine; BOUDRAA, Abdel-Ouahab (2015)In this work a new denoising scheme based on the empirical mode decomposition associated with a frequency analysis is introduced. Compared to classical approaches where the extracted modes are thresholded in time domain, ...
Local frequency and envelope estimation by Teager-Kaiser energy operators in white-light scanning interferometry SALZENSTEIN, Fabien; MONTGOMERY, Paul; BOUDRAA, Abdel-Ouahab (Optical Society of America, 2014)In this work, a new method for surface extraction in white light scanning interferometry (WLSI) is introduced. The proposed extraction scheme is based on the Teager-Kaiser energy operator and its extended versions. This ...
KHALDI, Kais; BOUDRAA, Abdel-Ouahab (IEEE, 2013)In this paper a new adaptive audio watermarking algorithm based on Empirical Mode Decomposition (EMD) is introduced. The audio signal is divided into frames and each one is decomposed adaptively, by EMD, into intrinsic ...
