Parametric Level Set Methods for Inverse Problems

WebNov 30, 2024 · It is known that Level Set Method (LSM) is numerical technique to track the interface and shape, which has been extensively used in many disciplines. The core of the LSM is to define a level set function with a higher-dimension to represent the structure, where the zero-level set is employed to represent the structural boundaries. WebLevel-set methods (LSM) are a conceptual framework for using level sets as a tool for numerical analysis of surfaces and shapes.The advantage of the level-set model is that one can perform numerical computations involving curves and surfaces on a fixed Cartesian grid without having to parameterize these objects (this is called the Eulerian approach). Also, … lonoke county historical museum
