Signed Distance Map Reinitialization.
Brute-force implementation of the reinitialization of the distance function. The following Hamilton-Jacobi equation is solved: d_tau + S(d) * ( |grad phi| - 1 ) = 0 d(x,0) = d_0(x) = phi(x,t) to steady state, with S(d) approximated by: s = d / ( sqrt( d^2 + |Dd|^2 * delta_x^2) )
Calculates gradient magnitude of phi using upwind-scheme. Performs PDE update using forward Euler time discretization.
- Parameters:
-
| phi | Input level set that should be redistanced into a signed distance grid. |
| psi | Output level set. That is the redistaned phi. |
| max_iterations | The maximum number of iterations allowed to do re-initialization. |
| stead_threshold | The threshold value used to test for steady state. |
