“…The following features and transformations have proven well in the context of pattern-recognition-based myoelectric control (cf. [81, p. 250-251]): -linear envelope [107], [104, p. 271], [76], [10], -zero crossings and variance [87], -integral absolute value, variance, zero crossing [94], -mean absolute value [6], its slope, wave form length, number of waveform slope sign changes, number of waveform zero crossings (Hudgins set of features) [45], -frequency spectrum via Fourier transform [26], [39], [93], random Fourier features [35], [34], as well as local frequency and phase content via short-time Fourier transform [41], [23,22], [91], -autoregressive coefficients [103], [14], [55], -cepstral coefficients [103], [14], -wavelet decomposition coefficients [23,22], [47], [67], [36], [8], [48], [84] and their Eigenvalues [66], -wavelet packet feature sets [23,22], motor unit action potentials (MUAPs) via wavelet packet transform and fuzzy C-means clustering [85], -signal energy (overall, within Hamming windows, within trapezoidal windows) as temporal features and spectral magnitude as well as spectral moments from short-time Thompson transform [91], -moving approximate entropy [2], andcontraction factors from fractal modeling [55], fractal dimensions [...…”
