Table 1.
Comparison of the performances of the two proposed ResNet + 2x-LSTM algorithms for young-age-trained and all-age-trained models. The table indicates the value of the coefficient of determination (R2), the root-mean-square error (RMSE) in millimeters (mm), the mean absolute percentage error with respect to the total length of the fascicles (in %), the average absolute frame difference (aaFD) of the individual subsegments in mm, and the average detection time (mean in seconds ± SD).
