Filters repeated objects based on the area size.

void NmsSortByArea(std::vector<DetectBox>& detBoxes, const float iouThresh, const IOUMethod method = UNION);

void NmsSortByArea(std::vector<ObjectInfo>& detBoxes, const float iouThresh, const IOUMethod method = UNION);

Parameter	Input/Output	Description
detBoxes	Input/Output	DetectBox (central point)/ObjectInfo (corner point) to be filtered. The filtered object information is output.
iouThresh	Input	Filtering threshold.
method	Input	IoU is calculated as follows: MAX: The overlapped area is divided by the larger one of the two areas. MIN: The overlapped area is divided by the smaller one of the two areas. UNION: The overlapped area is divided by the union of the two areas. DIOU: The value equals the value of UNION minus the IoU of the distances.
