Fig. 4From: Motor unit action potential conduction velocity estimated from surface electromyographic signals using image processing techniquesCV estimation comparison between the proposed IPE algorithm and the MLE algorithm proposed by Farina et al. [12], using simulated signals with different CV values—3 m/s (medium gray), 4 m/s (light gray), and 5 m/s (dark gray)—, different levels of noise: a noise free; b 30 dB SNR; c 20 dB SNR; d 16 dB SNR; and e 12 dB SNR, and different level of force: 20 % MVC, 40 % MVC and 60 % MVC. The black diagonal dashed lines are the identity lines. Each MLE–IPE pair of CV measurements (one dot) is associated with one simulated signalBack to article page
