Singular spectrum analysis for effective feature extraction in hyperspectral imaging [PDF]

open access: yes, 2014
As a very recent technique for time series analysis, Singular Spectrum Analysis (SSA) has been applied in many diverse areas, where an original 1D signal can be decomposed into a sum of components including varying trends, oscillations and noise ...

An Alternative Formulation for the Empirical Mode Decomposition [PDF]

open access: yesIEEE Transactions on Signal Processing, 2012
The Empirical Mode Decomposition (EMD) is a relatively new adaptive method for multicomponent signal representation which allows for analyzing nonlinear and nonstationary signals. In spite of its lack of mathematical foundations, very few papers are dedicated to defining new decompositions that would preserve the interesting properties of the EMD while

Empirical mode decomposition with missing values [PDF]

open access: yesSpringerPlus, 2016
This paper considers an improvement of empirical mode decomposition (EMD) in the presence of missing data. EMD has been widely used to decompose nonlinear and nonstationary signals into some components according to intrinsic frequency called intrinsic mode functions.

Multi Sensor Image Fusion using Empirical Mode Decomposition [PDF]

open access: yes, 2013
Image fusion is a process of combining relevant information from two or more images from different sensors based on certain algorithm. Many algorithms have been proposed for pixel level image fusion.

Improved EMD Using Doubly-Iterative Sifting and High Order Spline Interpolation [PDF]

open access: yes, 2008
Empirical mode decomposition (EMD) is a signal analysis method which has received much attention lately due to its application in a number of fields. The main disadvantage of EMD is that it lacks a theoretical analysis and, therefore, our understanding ...

Artifact reduction in multichannel pervasive EEG using hybrid WPT-ICA and WPT-EMD signal decomposition techniques [PDF]

open access: yes, 2014
In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and ...

Sparse Reconstruction for Enhancement of the Empirical Mode Decomposition-Based Signal Denoising

open access: yesIEEE Access, 2020
Effective signal denoising methods are essential for science and engineering. In general, denoising algorithms may be either linear or non-linear. Most of the linear ones are unable to remove the noise from the real-world measurements.

EMD-Based Filtering Using Similarity Measure Between Probability Density Functions of IMFs [PDF]

open access: yes, 2014
This paper introduces a new signal-filtering which combines the empirical mode decomposition (EMD) and a similarity measure. A noisy signal is adaptively broken down into oscillatory components called intrinsic mode functions (IMFs) by EMD followed by an
