CalcIou

Calculates the IOU value.

float CalcIou(DetectBox a, DetectBox b, IOUMethod method = UNION);

float CalcIou(ObjectInfo a, ObjectInfo b, IOUMethod method = UNION);

Parameter	Input/Output	Description
a	Input	DetectBox (central point)/ObjectInfo (corner point)
b	Input	DetectBox (central point)/ObjectInfo (corner point)
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.
