Class AlgorithmConstrainedELSUNCOAR3D.MatrixListItem

java.lang.Object
gov.nih.mipav.model.algorithms.registration.AlgorithmConstrainedELSUNCOAR3D.MatrixListItem
All Implemented Interfaces:
Comparable<AlgorithmConstrainedELSUNCOAR3D.MatrixListItem>
Enclosing class:
AlgorithmConstrainedELSUNCOAR3D
class AlgorithmConstrainedELSUNCOAR3D.MatrixListItem extends Object implements Comparable<AlgorithmConstrainedELSUNCOAR3D.MatrixListItem>
Helper class to make it easy to store the necessary information about a minimum. Stores the "point", or vector at which the minimum was reached; the "cost", or value of the cost function at that minimum; and the matrix, which was the true input into the cost function and represents the transformation that gives the minimum cost of differences between the images. Implements Comparable, so that a list of MatrixListItems can be sorted using Java's sort.

  • Field Details

    • cost

      protected double cost
      Cost of function at this minimum.

    • halfMatrix

      protected TransMatrixd halfMatrix
      Matrix with the best transformation divided by half. Might be null.

    • initial

      protected double[] initial
      Rotations, translations, scales, and skews that make up transformation.

    • matrix

      protected TransMatrixd matrix
      Matrix that gives best transformation.

    • midsagMatrix

      protected TransMatrixd midsagMatrix
      Matrix with the best transformation's z rot and xy translations. Might be null.

  • Constructor Details

    • MatrixListItem

      protected MatrixListItem(double _cost)
      Creates new minimum object, with identity transMatrix and a given cost.
      Parameters:
      _cost - Cost of this minimum.

    • MatrixListItem

      protected MatrixListItem(double _cost, TransMatrixd _matrix, double[] _initial)
      Creates new minimum object, setting the data and copying the point array explicitly.
      Parameters:
      _cost - Cost of this minimum.
      _matrix - Matrix that gives best transformation.
      _initial - Rotations, translations, scales, and skews that make up transformation.

  • Method Details

    • compareTo

      public int compareTo(AlgorithmConstrainedELSUNCOAR3D.MatrixListItem o)
      Necessary to implement so that list may be sorted. Returns -1 if this cost is less than the parameter's cost; 1 if this cost is greater than the parameter's cost; and 0 if they are equal.
      Specified by:
      compareTo in interface Comparable<AlgorithmConstrainedELSUNCOAR3D.MatrixListItem>
      Parameters:
      o - MatrixListItem to compare to.
      Returns:
      -1 if this is less than, 1 if greater than, 0 if equal.

    • toAbridgedString

      public String toAbridgedString()
      Creates string of this object with just first 6DOF and cost.
      Returns:
      Readable string representation of this object.

    • toString

      public String toString()
      Creates readable string of this object, including cost, matrix, and point with its meanings.
      Overrides:
      toString in class Object
      Returns:
      Readable string representation of this object.
