A Locally Gradient-Preserving Reinitialization for Level Set Functions
The level set method commonly requires a reinitialization of the level set function due to interface motion and deformation. We extend the traditional technique for reinitializing the level set function to a method that preserves the interface gradient. The gradient of the level set function represents the stretching of the interface, which is of critical importance inmany physical applications...
متن کاملThe Augmented Fast Marching Method for Level Set Reinitialization∗
Including derivative information in the modelling of moving interfaces has been proposed as one method to increase the accuracy of numerical schemes with minimal additional cost. Here a new level set reinitialization technique using the fast marching method is presented. This augmented fast marching method will calculate the signed distance function and up to the secondorder derivatives of the ...
متن کاملDistance Field Reinitialization for Localized Level Set Methods
Bibliography 83 Preface Since their introduction by Osher and Sethian [14], level set methods have been used to solve a wide range of problems, including, but not limited to • Photolithography Development, Etching and Deposition in Semi-conductor Manufacturing (see [2]), • Robotic Navigation with Constraints (see [9]). More examples of applications, further references, and a survey can be found...
متن کاملOptimal control for reinitialization in finite element level set methods
A new optimal control control problem that incorporates the residual of the Eikonal equation into its objective is presented. The formulation of the state equation is based on the level set transport equation but extended by an additional source term, correcting the solution so as to minimize the objective functional. The method enforces the constraint so that the interface cannot be displaced....
متن کاملDifferential equation based constrained reinitialization for level set methods
A partial differential-equation based reinitialization method is presented in the framework of a localized level set method. Two formulations of the new reinitialization scheme are derived. These formulations are modifications of the partial differential equation introduced by Sussman et al. [J. Comp. Phys. 114 (1994), 146-159] and, in particular, improvements of the second-order accurate modif...
