Constructor Details

AssociatedPair

public AssociatedPair()

AssociatedPair

public AssociatedPair(double x1,
 double y1,
 double x2,
 double y2)

Creates a new associated point from the two provided points.

Parameters:

x1 - image 1 location x-axis.

y1 - image 1 location y-axis.

x2 - image 2 location x-axis.

y2 - image 2 location y-axis.

AssociatedPair

public AssociatedPair(Point2D_F64 p1,
 Point2D_F64 p2)

AssociatedPair

public AssociatedPair(Point2D_F64 p1,
 Point2D_F64 p2,
 boolean newInstance)

Allows features to either be copied or saved as references.

Parameters:

p1 - image 1 location

p2 - image 2 location

newInstance - Should it create new points or save a reference to these instances.
