Fitting 𝐶² Continuous Parametric Surfaces to Frontiers Delimiting Physiologic Structures

Figure 5

Parametric surfaces fitted to the 𝑥−𝑦−𝑧 coordinates of the regularized polygonal meshes shown in Figure 4. (a) Right ventricular cavity; (b) left ventricular cavity; (c) epicardium. Gray: parametric surface. Red: Surface composed of triangles array generated from the brick wall texture of Figure 2.
