VMD-based denoising methods for surface electromyography signals

Since noise is inevitably introduced during the measurement process of surface electromyographic (sEMG) signals, two novel methods for denoising based on the variational mode decomposition (VMD) method were proposed in this work. Prior to this study, there has been no literature relating to how VMD is applied to sEMG denoising.The first proposed method uses the VMD method to decompose the signal into multiple variational mode functions (VMFs),...
