2. The two columns of the Jacobian DS{x) are tangent vectors to S at the point S(x). Their cross product is a normal vector.
3. We assume that the surface is visible (in front of the retinal plane) hence u 0.
4. Corresponding to Dupuis and Oliensis' Solution, if one exists.
5. Dirichlet conditions consists in fixing the values ofthe Solutions.
6. Neumann conditions consists in fixing the values ofthe derivatives the Solutions
7. Dirichlet (respectively, Neumann) boundary conditions require the knowledge of the exact values of the Solution (respectively, the exact values ofVu{x) ? n{x), where n{x) is the unit inward normal vector to dO. at the point x) on the boundary of the image. In the SFS problem, we rarely have such data at our disposal.
