The developed MATLAB toolbox PPGFeat can automaticallyidentify the fiducial points. The PPGFeat toolbox allows for theapplication of various preprocessing techniques, such as the useof a filter, smoothing, removing baseline drift, the possibility ofcalculating PPG derivatives, and implementing algorithms fordetecting and highlighting PPG fiducial points. The results can beused to generate more statistically accurate features for furtheranalysis of the PPG signals.

The features table generated by the PPGFeat toolbox providesthe fiducial points magnitude and time domain values of the PPG,VPG and APG. A total of 30 features are generated, and include themagnitude features O, S, N, D, Min2, w, x, y, z, a, b, c, d, e, f, andtime domain features O_t, S_t, N_t, D_t, Min2_t, w_t, x_t, y_t, z_t,a_t, b_t, c_t, d_t, e_t, and f_t.
