Class AlgorithmConstrainedELSUNCOAR3D.MatrixListItem

  • All Implemented Interfaces:
    java.lang.Comparable<AlgorithmConstrainedELSUNCOAR3D.MatrixListItem>
    Enclosing class:
    AlgorithmConstrainedELSUNCOAR3D
    class AlgorithmConstrainedELSUNCOAR3D.MatrixListItem
extends java.lang.Object
implements java.lang.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.

        compareTo in interface java.lang.Comparable<AlgorithmConstrainedELSUNCOAR3D.MatrixListItem>
        Parameters:
        o - MatrixListItem to compare to.
        Returns:
        -1 if this is less than, 1 if greater than, 0 if equal.
