float bdgl_region_algs::earth_mover_distance	(	vdgl_digital_region_sptr const &	r1,
		vdgl_digital_region_sptr const &	r2
	)		`[static]`

Computes a variant of the earth mover's distance with respect to intensity.

Computes the maximum average distance between the intensity samples in two regions.

Returns -1 if the distance cannot be reliably calculated.

float bdgl_region_algs::intensity_distance	(	vdgl_digital_region_sptr const &	r1,
		vdgl_digital_region_sptr const &	r2
	)		`[static]`

Computes the intensity distance between two regions.

Returns -1 if the distance cannot be reliably calculated.

Definition at line 38 of file bdgl_region_algs.cxx.

float bdgl_region_algs::mahalanobis_distance	(	vdgl_digital_region_sptr const &	r1,
		vdgl_digital_region_sptr const &	r2
	)		`[static]`

Computes the Mahalanobis distance between two regions.

Finds the Mahalanobis distance between the intensity distributions of two regions.

Returns -1 if the distance cannot be reliably calculated.

If there are not enough pixels in either or both regions to reliably determine the distance then -1 is returned.

bool bdgl_region_algs::merge	(	vdgl_digital_region_sptr const &	r1,
		vdgl_digital_region_sptr const &	r2,
		vdgl_digital_region_sptr &	rm
	)		`[static]`

Merges two digital regions and returns false if there is failure.
