An improved EMD adaptive denoising and feature extraction algorithm

2019 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2019
The noise is often accompanied in the process of extracting the signal from the engineering application which will cause a large error in the processing of the signal and interferer the judgment. Aiming at this problem, this paper proposes an improved EMD adaptive removing noise and feature extraction algorithm.

Denoising Algorithm Based on EMD with Adaptive Adjustment of Coefficients

2019 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2019
This paper deals with the denoising algorithm based on EMD with adaptive adjustment of the coefficients depending on the noise level. It is compared with the known denoising algorithms based on EMD, wavelets and Wiener filter. The evaluation of the filtration quality was performed.

Improved algorithm for image decomposition based on bidimensional EMD

SPIE Proceedings, 2007
According to the system intrinsic quality of self-comparability and the empirical mode decomposition algorithm of completeness and stability, an improvement algorithm for EMD image decomposition is presented. It is integrity, fast and effective. Some aspects were improved that bidimensional interpolation methods and end conditions of getting intrinsic ...

An Improved Symbol Entropy Algorithm Based on EMD for Detecting VT and VF

2017
In this paper the improved symbol entropy algorithm based on empirical mode decomposition (EMD) was proposed to detect ventricular tachycardia (VT) and ventricular fibrillation (VF). The original symbol entropy arithmetic needed longer time series to distinguish VT and VF by high accuracy while the algorithm we proposed can distinguish VT and VF in ...
