Description |
|---|---|---|---|
|
hrPrev |
|
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipBoundingBoxes |
|
Container of bounding boxes to apply the non maximum supresion (ContainerType_Vector_TcVnRectangle_DINT) | |
|
ipScores |
|
Container of coreeponding score for each bounding box (ContainerType_Vector_REAL) | |
|
ipDestIndcies |
|
Container of the kept indcies after apply the non maximum suppression (ContainerType_Vector_DINT) | |
|
fScoreThreshold |
float |
|
A threshold [0.0 to 1.0] used to filter the bounding boxes by score |
|
fOverlapThreshold |
float |
|
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 |
|
ipClassIndcies |
nullptr |
Container of corresponding set of class indcies (ContainerType_Vector_DINT) | |
|
fEta |
float |
1.0f |
An adjustable threshold [0.0 to 1.0] used to dynamically reduce the overlap threshold during processing. Setting it to 1 maintains a constant value for the overlap threshold |
|
nTopK |
LONG |
0 |
The maximum number of bounding boxes with the highest scores to undergo the suppression algorithm (must be >= 0). Setting it to zero applies the algorithm to all bounding boxes |
