An Efficient ECG Denoising Method Based on Empirical Mode Decomposition, Sample Entropy, and Improved Threshold Function

Abstract: The electrocardiogram (ECG) signal can easily be affected by various types of noises while being recorded, which decreases the accuracy of subsequent diagnosis. Therefore, the efficient denoising of ECG signals has become an important research topic. In the paper, we proposed an efficient ECG denoising approach based on empirical mode decomposition (EMD), sample entropy, and improved threshold function. This method can better remove the noise of ECG signals and provide better diagnosis service for the computer… Show more

“…As a result, it should be combined with another approach to achieve the best results. The EMD's main flaws are its noise sensitivity and the mode mixing property, which introduces error into the observed signal [35]. To address these issues, Huang suggested an Ensemble Empirical Mode Decomposition (EEMD) system [20], which was later improved [21], resulting in a numerically negligible error.…”

“…Heating equipment in process systems such as refineries is generally divided into two general categories of furnaces and heat exchangers [14][15][16][17][18][19]. The difference between a furnace and a heat exchanger is in the heating source [20][21][22][23], which means that the heating source is liquid and gas [24][25][26][27][28][29]. While in a heat exchanger, the heating source is a hot fluid.…”

“…The prominent influence of carbon dioxide-based enhanced oil recovery methods has been studied to enhance the recovery factor in tight oil reservoirs [95][96][97][98][99]. Based on several studies, carbon dioxide is stored in underground formations and helps to enhance oil recovery [100][101][102].…”
