Classifying EMG signals using T-F representation and SVD [for artificial limb control]
Li-Yu Cai, Zhizhong Wang, Haihong Zhang · 2003
A surface EMG signal classification method based on time-frequency representation and singular value decomposition is presented. The short-time Fourier transform and wavelet transform are employed to obtain the signals' time-frequency representation, from which the singular value decomposition technique is used to extract features for neural network based classification.
