template<class srcT , class destT >

void vil3d_quad_distance_function	(	const vil3d_image_view< srcT > &	src,
		double	ai,
		double	aj,
		double	ak,
		vil3d_image_view< destT > &	dest
	)		`[inline]`

Apply quadratic distance transform.

dest(x,y,z)=min_i,j,k (src(x+i,y+j,z+k)+ai(i^2)+aj(j^2)+ak(k^2))

template<class srcT , class destT , class posT >

void vil3d_quad_distance_function	(	const vil3d_image_view< srcT > &	src,
		double	ai,
		double	aj,
		double	ak,
		vil3d_image_view< destT > &	dest,
		vil3d_image_view< posT > &	pos
	)		`[inline]`

Apply quadratic distance transform, storing relative position of minima.

dest(x,y,z)=min_i,j,k (src(x+i,y+j,z+k)+ai(i^2)+aj(j^2)+ak(k^2)) (pos(x,y,0),pos(x,y,1),pos(x,y,2)) gives the position (x+i,y+j,z+k) leading to minima

void vil3d_quad_distance_function_i	(	const vil3d_image_view< srcT > &	src,
		double	ai,
		vil3d_image_view< destT > &	dest
	)		`[inline]`

Apply quadratic distance transform along each row of src.

dest(x,y,z)=min_i (src(x+i,y,z)+ai(i^2))

		double	ai,
		vil3d_image_view< destT > &	dest,
		vil3d_image_view< posT > &	pos
	)		`[inline]`

Apply quadratic distance transform along i, storing relative position of minima.

dest(x,y,z)=min_i (src(x+i,y,z)+ai(i^2)) (pos(x,y,0)) gives the position (x+i,y,z) leading to minima
