virtual

Destructor.

Member Function Documentation

◆ freeze()

void jevois::dnn::PostProcessorDetectOBB::freeze ( bool  doit)
overridevirtual

Freeze/unfreeze parameters that users should not change while running.

Implements jevois::dnn::PostProcessor.

Definition at line 35 of file PostProcessorDetectOBB.C.

◆ latestDetectionsOBB()

std::vector< jevois::ObjDetectOBB > const & jevois::dnn::PostProcessorDetectOBB::latestDetectionsOBB ( ) const

Get the latest detections, use with caution, not thread-safe.

This returns a reference to our internal vector of detections. That vector will get overwritten every time process() is called. It is ok to use this after you have called process() on a given frame, or, if using a Pipeline, after you have called Pipeline::process(). Do not hold this ref past the end of the current video frame. If you need to keep a persistent copy of the data, make a deep copy of the vector.
