Figure 8

Bland–Altman plots of the agreement between reference values (ground truth) and predicted top layers thicknesses, using the peak-based DRS features and the GPR model, for (a) fat on top of muscle tissue and (b) muscle on top of fat tissue. The black line shows the mean difference between the predicted and true layer thickness, the dashed lines show the 95% confidence interval for the agreement (± 1.96SD).
