Method Details

fit

public void fit(List<Point3f> points,
 Mark mark,
 Dimensions dimensions)
         throws PointsFitterException

Description copied from class: PointsFitter

Fits a mark to a set of points within given dimensions.

Specified by:

fit in class PointsFitter

Parameters:

points - the list of points to fit the mark to

mark - the mark to be fitted (will be modified)

dimensions - the dimensions within which the fitting occurs

Throws:

PointsFitterException - if an error occurs during the fitting process

minNumPoints

protected abstract int minNumPoints()

Returns the minimum number of points required for fitting.

Returns:

the minimum number of points

applyCoefficientsToMark

protected abstract void applyCoefficientsToMark(cern.colt.matrix.DoubleMatrix2D matrixV,
 Mark mark,
 Dimensions dimensions)
                                         throws PointsFitterException

Applies the calculated coefficients to the mark.

Parameters:

matrixV - the matrix of coefficients

mark - the Mark to update

dimensions - the Dimensions of the image

Throws:

PointsFitterException - if there's an error applying the coefficients

createDesignMatrix

protected abstract cern.colt.matrix.DoubleMatrix2D createDesignMatrix(List<Point3f> points)

Creates the design matrix from the input points.

Parameters:

points - the list of Point3f to use for creating the design matrix

Returns:

the design matrix as a DoubleMatrix2D
