Class RANSAC.BestFitStoppingCondition

java.lang.Object

org.openimaj.math.model.fit.RANSAC.BestFitStoppingCondition

All Implemented Interfaces:

RANSAC.StoppingCondition

Enclosing class:

RANSAC<I,D,M extends EstimatableModel<I,D>>

public static class RANSAC.BestFitStoppingCondition
extends Object
implements RANSAC.StoppingCondition

Stopping condition that allows the RANSAC algorithm to run until all the iterations have been exhausted. The fitData method will return true if there are at least as many inliers as datapoints required to estimate the model, and the model will be the one from the iteration that had the most inliers.

Method Detail

init

public boolean init(List<?> data,
                    EstimatableModel<?,?> model)

Description copied from interface: RANSAC.StoppingCondition

Initialise the stopping condition if necessary. Return false if the initialisation cannot be performed and RANSAC should fail

Specified by:

init in interface RANSAC.StoppingCondition

Parameters:

data - The data being fitted

model - The model to fit

Returns:

true if initialisation is successful, false otherwise.

shouldStopIterations

public boolean shouldStopIterations(int numInliers)

Description copied from interface: RANSAC.StoppingCondition

Should we stop iterating and return the model?

Specified by:

shouldStopIterations in interface RANSAC.StoppingCondition

Parameters:

numInliers - number of inliers in this iteration

Returns:

true if the model is good and iterations should stop

finalFitCondition

public boolean finalFitCondition(int numInliers)

Description copied from interface: RANSAC.StoppingCondition

Should the model be considered to fit after the final iteration has passed?

Specified by:

finalFitCondition in interface RANSAC.StoppingCondition

Parameters:

numInliers - number of inliers in the final model

Returns:

true if the model fits, false otherwise
