NumberNewDiaObjectsMetricTask#
NumberNewDiaObjectsMetricTask computes the number of DIAObjects created when processing data through source association (as the ap_association.numNewDiaObjects metric).
It requires task metadata as input, and can operate at image-level or coarser granularity.
Processing summary#
NumberNewDiaObjectsMetricTask reads AssociationTask statistics from task metadata associated with one or more processed images.
It uses these statistics to count the number of new DIAObjects added when processing those images.
