Detailed Description

base class for appearance models that use the negative sum of squared differences ("SSD") or L2 norm of the difference between the initial and current pixel values (original or modified) as the similarity measure

Member Function Documentation

double SSDBaseDist::accum_dist	(	const double &	a,
		const double &	b,
		int
	)		const

inline

Partial euclidean distance, using just one dimension.

This is used by the kd-tree when computing partial distances while traversing the tree.

Squared root is omitted for efficiency.

double SSDBaseDist::operator()	(	const double *	a,
		const double *	b,
		size_t	size,
		double	worst_dist = `-1`
	)		const

overridevirtual

Squared Euclidean distance functor, optimized version.

Compute the squared Euclidean distance between two vectors.

This is highly optimized, with loop unrolling, as it is one of the most expensive inner loops.

The computation of squared root at the end is omitted for efficiency.

Reimplemented from AMDist.
