                                                            throws OperationFailedException

Reduce a list of elements (each with a confidence score and a label) to a smaller-list.

It is not guaranteed that the resulting list will have fewer elements than the input list, but never more.

Parameters:

elements - proposed bounding-boxes with scores.

extent - an area in which all elements must exclusively reside.

executionTimeRecorder - records the execution time of particular operations.

Returns:

the outcome of the operation, indicating which elements are retained / removed / added.

Throws:

OperationFailedException - if anything goes wrong.
