Fitting 𝐶² Continuous Parametric Surfaces to Frontiers Delimiting Physiologic Structures

Table 1

Parameters of the surface fitting. Number of polygons: number of polygons in the polygonal surfaces of Figure 2. 𝑁_𝑢, 𝑁_𝑣: number of elements along the 𝑢 and 𝑣 coordinates of the parametric plane. Stiffness: parameter 𝜆 in (13).
