Figure 5

The images shows the SAS boundary after 12 hours. The upper row shows the observations with following preprocessing left to right: Raw observations, projection of CSF value onto the boundary, Gaussian smoothing. The middle row shows the corresponding states with the regularization parameters α, β, γ = (10−6, 1.0, 1.0). The bottom row shows the corresponding states with the regularization parameters α, β, γ = (10−6, 100.0, 100).
