Constructor Detail

Zhang99OptimizationFunction

public Zhang99OptimizationFunction(Zhang99ParamAll param,
                                   java.util.List<Point2D_F64> grid,
                                   java.util.List<CalibrationObservation> observations)

Configurations the optimization function.

Parameters:

param - Storage for calibration parameters. Effectively specifies the number of target views and radial terms

grid - Location of points on the calibration grid. z=0

observations - calibration point observation pixel coordinates

Method Detail

getNumOfInputsN

public int getNumOfInputsN()

Description copied from interface: FunctionNtoM

Number of input elements. Typically the parameters you are optimizing.

Specified by:

getNumOfInputsN in interface FunctionNtoM

Returns:

number of input elements

getNumOfOutputsM

public int getNumOfOutputsM()

Description copied from interface: FunctionNtoM

Number of output elements. Typically the functions that are being optimized.

Specified by:

getNumOfOutputsM in interface FunctionNtoM

Returns:

number of output elements

process

public void process(double[] input,
                    double[] output)

Description copied from interface: FunctionNtoM

Processes the input to compute the values found in the output array. The output's meaning depends on the application. For least-squares it is the residual error. See UnconstrainedLeastSquares.

The user can modify the input parameters here and the optimizer must use those changes.

Specified by:

process in interface FunctionNtoM

Parameters:

input - Parameters for input model.

output - Storage for the output give the model.

process

public void process(Zhang99ParamAll param,
                    double[] residuals)
