Type Members

1. class BreezeCGPoissonSolver[A] extends LinearSystemPoissonSolver[A]

   

   conjugate gradient solver from breeze (for completeness, do not use, has no preconditioning and is slow, rather use PreconditionedConjugateGradient and maybe ConjugateGradient)

2. class ConjugateGradientPoissonSolver[A] extends LinearSystemPoissonSolver[A]

   

   conjugate gradient solver for a Poisson system, no preconditioning (only for very small systems, prefer Preconditioned CG)

3. class DenseLinearSystemPoissonSolver[A] extends LinearSystemPoissonSolver[A]

   

   solve a Poisson equation in the image domain using a dense linear Cholesky solver (due to the dense matrix only for small systems and a lot of memory)

4. class GenericMultigridPoissonSolver[A] extends ImageDomainPoissonSolver[A]

   

   Multigrid algorithm to solve Poisson's equation in the image domain for generic pixel type A (efficient but may not fully converge with complicated boundaries)

5. trait ImageDomainPoissonSolver[A] extends AnyRef

   

   Solve Poisson's equation in an image domain with (arbitrary) Dirichlet boundary conditions

6. abstract class LinearSystemPoissonSolver[A] extends ImageDomainPoissonSolver[A]

   

   transform a Poisson equation in the image domain to a linear system (finite differences)

7. case class MultigridParameters(vCycles: Int, minSize: Int, prepareIterations: Int, solverIterations: Int, occlusionCorrectionIterations: Int, correctionIterations: Int) extends Product with Serializable

   

   Multigrid parameters

8. class Permutation extends AnyRef

   

   permutation

9. sealed trait PermutationStrategy extends AnyRef

   

   permutation strategy for the Sparse Cholesky decomposition

10. class PreconditionedConjugateGradientPoissonSolver[A] extends LinearSystemPoissonSolver[A]

    

    conjugate gradient solver for a Poisson system, uses incomplete Cholesky preconditioning (considerably faster than CG)

11. case class SHIndex(l: Int, m: Int) extends Product with Serializable

    

    two-values index of Spherical Harmonics function (l, m)

12. class SparseCholeskyPoissonSolver[A] extends LinearSystemPoissonSolver[A]

    

    solve a Poisson equation using a sparse Cholesky decomposition (efficient for small systems, use PCG for larger systems)
