NumberUnassociatedDiaObjectsMetricTask¶
NumberUnassociatedDiaObjectsMetricTask computes the number of DIAObjects that are not updated when processing data through source association (as the ap_association.numUnassociatedDiaObjects metric).
It requires task metadata as input.
While the task can operate at image-level or coarser granularity, the current algorithm may double-count objects and should not be run on multiple visits.
Processing summary¶
NumberUnassociatedDiaObjectsMetricTask reads AssociationTask statistics from task metadata associated with one or more processed images.
It uses these statistics to count the number of unassociated DIAObjects when processing those images.
