public abstract class WithResolutionBase<T extends FeatureInputWithResolution>
extends FeatureUnaryGeneric<T>

Base class for a feature that requires input resolution to be calculated.

This class provides a framework for features that depend on image resolution for their calculations. It handles cases where resolution might be missing.

Method Details

calculate

public final double calculate(FeatureCalculationInput<T> input)
                       throws FeatureCalculationException

Calculates the feature value, handling cases where resolution might be missing.

Specified by:

calculate in class Feature<T extends FeatureInputWithResolution>

Parameters:

input - the input for feature calculation

Returns:

the calculated feature value

Throws:

FeatureCalculationException - if an error occurs during calculation

calculateWithResolution

protected abstract double calculateWithResolution(double value,
 Resolution resolution)
                                           throws FeatureCalculationException

Calculates the feature value using the provided value and resolution.

Parameters:

value - the input value to be used in the calculation

resolution - the resolution to be used in the calculation

Returns:

the calculated feature value

Throws:

FeatureCalculationException - if an error occurs during calculation

isAcceptMissingResolution

public boolean isAcceptMissingResolution()

Whether to return Double.NaN (if true) or throw an exception (if false) when image resolution is missing.

setAcceptMissingResolution

public void setAcceptMissingResolution(boolean acceptMissingResolution)

Whether to return Double.NaN (if true) or throw an exception (if false) when image resolution is missing.
