Feature extraction emg signal
WebOct 18, 2024 · The surface EMG signals are used as input to time–frequency (TF) representation for the signal-to-image conversion. The short-time Fourier transform (STFT) is considered in TF representation. Various deep features are extracted from the TFI by using the AlexNet and VGG16 models. WebKeywords: Prosthesis, EMG Signal classification, Feature extraction, Signal processing, Mother wavelet Functions. I. I NTRODUCTION Classification and identification of biosignals is still a challenge in several areas. EMG signals are complex due to the non-stationary characteristics and subject dependency of the signals.
