Inputs

Name	Type	Description
ipBoundingBoxes	ITcVnContainer	Container of bounding boxes to apply the non maximum supresion (ContainerType_Vector_TcVnRectangle_DINT)
ipScores	ITcVnContainer	Container of coreeponding score for each bounding box (ContainerType_Vector_REAL)
ipDestIndcies	Reference To ITcVnContainer	Container of the kept indcies after apply the non maximum suppression (ContainerType_Vector_DINT)
fScoreThreshold	REAL	A threshold [0.0 to 1.0] used to filter the bounding boxes by score
fOverlapThreshold	REAL	A threshold [0.0 to 1.0] that determines the minimum degree of intersection over union (IoU) required for bounding boxes to be considered overlapping
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
