    • Schrödinger Operator for Sparse Approximation of 3D Meshes 

      Choukroun, Yoni; Pai, Gautam; Kimmel, Ron (The Eurographics Association, 2017)
      We introduce a Schrödinger operator for spectral approximation of meshes representing surfaces in 3D. The operator is obtained by modifying the Laplacian with a potential function which defines the rate of oscillation of ...
