Comparison of mean curvature evolution of PDE approximation and fast LS evolution. This shows the initial condition and evolution of fast LS (white line) and numerical PDE approximation (black line). (A) Test initial condition for validation of mean curvature motion fast LS evolution against numerical PDE approximation. The test region contains positive, negative, and zero curvature regions and singularities as well. (B) State of evolution fast LF at Nit=20 and PDE approximation at T=56.8. (C) State of evolution fast LF at Nit=40 and PDE approximation at T=190.8. (D) State of evolution fast LF at Nit=60 and PDE approximation at T=405.6. (E) State of evolution fast LF at Nit=80 and PDE approximation at T=706.8.
