Class MultiMetrics.MetricsSummary

java.lang.Object

net.imglib2.algorithm.metrics.segmentation.MultiMetrics.MetricsSummary

Enclosing class:

MultiMetrics

protected static class MultiMetrics.MetricsSummary
extends Object

An object holding the sum of TP, FP, FN and IoU values, accumulated over the T dimension. These quantities are then used to compute all other metrics by calling getScores().

Method Detail

addPoint

public void addPoint(MultiMetrics.MetricsSummary otherMetrics)

Add the otherMetrics values to the aggregate of the current object.

Parameters:

otherMetrics - MetricsSummary containing values to add to the aggregates

addPoint

public void addPoint(int tp,
                     int fp,

                     double sumIoU)

Add the values to the aggregates.

Parameters:

tp - Value to add to the TP aggregate

fp - Value to add to the FP aggregate

fn - Value to add to the FN aggregate

sumIoU - Value to add to the IoU aggregate
