Member Function Documentation

virtual double ComputeDistance	(	const Feature &	f1,
		const Feature &	f2
	)			const [pure virtual]

Compute distance.

Implemented in L1DistanceComputer, and L2DistanceComputer.

double ComputeDistance	(	const Feature &	f1,
		const Feature &	f2,
		double	max_distance
	)			const [virtual]

Quickly compute min(actual_distance(f1, f2), max_distance).

This is the same as ComputeDistance, except it will stop calculating things when it knows the distance will be greater than max_distance.

Reimplemented in L1DistanceComputer, and L2DistanceComputer.
