ARGUMENTSkp1, kp2
FUNCTIONKeyPoint_overlap
RETURN TYPEnumber
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

This method computes overlap for pair of keypoints. Overlap is the ratio between area of keypoint regions' intersection and area of keypoint regions' union (considering keypoint region as circle). If they don't overlap, we get zero. If they coincide at same location with same size, we get 1.

KeyPoint_overlap(kp1: KeyPoint, kp2: KeyPoint): number;
kp1

First keypoint

kp2

Second keypoint

Returns

The number result.
