Detailed Description

template<class TLabelObject>
class otb::Functor::MergeLabelObjectFunctor< TLabelObject >

Merge two LabelObjects.

This functor merges the two inputs label objects into a third label object where the Run have been merged. The resulting label object holds data from first input label object copied via the CopyDataFrom() method.

Please note that if the two input label objects are disjoint, the resulting label object will have more than one connected component.

This functor is thread safe.
