All Implemented Interfaces:

FitShapeToPoints<Point2D_F64,ConicGeneral_F64>, FitShapeToPoints_F64<Point2D_F64,ConicGeneral_F64>

public class FitConicAtA_F64
extends Object
implements FitShapeToPoints_F64<Point2D_F64,ConicGeneral_F64>

Fit's a parabola to a set of points by finding the null space of A^T*A. This is faster but less numerically stable than techniques which don't explicitly square the matrix.

public FitConicAtA_F64()

Method Details

process

public boolean process(List<Point2D_F64> points,
 ConicGeneral_F64 output)

Fits the conic to the points. Strongly recommended that you transform the points such that they have zero mean and a standard deviation along x and y axis, independently.

Specified by:

process in interface FitShapeToPoints<Point2D_F64,ConicGeneral_F64>

Parameters:

points - (Input) points

output - (Output) found conic

Returns:

true if successful or false if it failed

process

public boolean process(List<Point2D_F64> points,
 double[] weights,
 ConicGeneral_F64 output)

Fits the conic to the weighted set of points. Strongly recommended that you transform the points such that they have zero mean and a standard deviation along x and y axis, independently.

Specified by:

process in interface FitShapeToPoints_F64<Point2D_F64,ConicGeneral_F64>

Parameters:

points - (Input) points

output - (Output) found conic

weights - (Input) Weight of each point.

Returns:

true if successful or false if it failed
