EMD VIA MEMD: MULTIVARIATE NOISE-AIDED COMPUTATION OF STANDARD EMD [PDF]
Advances in Adaptive Data Analysis, 2013 A noise-assisted approach in conjunction with multivariate empirical mode decomposition (MEMD) algorithm is proposed for the computation of empirical mode decomposition (EMD), in order to produce localized frequency estimates at the accuracy level of instantaneous frequency.

An EMD-based data hiding scheme for JPEG images
Connection Science, 2021 As a commonly used image format, JPEG image is popularly used as the carrier for data hiding. After analyzing the virtue of the exploiting-modification-direction (EMD) scheme, which is designed for the spatial domain, this paper reforms its extraction ...

Speech Enhancement via EMD [PDF]
EURASIP Journal on Advances in Signal Processing, 2008 In this study, two new approaches for speech signal noise reduction based on the empirical mode decomposition (EMD) recently introduced by Huang et al. (1998) are proposed. Based on the EMD, both reduction schemes are fully data-driven approaches. Noise signal is decomposed adaptively into oscillatory components called intrinsic mode functions (IMFs ...
