Function Documentation

template<class T >

double vimt3d_trilin_interp_raw	(	const vimt3d_image_3d_of< T > &	image,
		const vgl_point_3d< double > &	p,
		unsigned	plane = 0
	)		[inline]

Compute trilinear interpolation at p(x,y,z) in world coordinates, no bound checks.

Interpolates given plane of image.image() at image.world2im(p).

template<class T >

double vimt3d_trilin_interp_safe	(	const vimt3d_image_3d_of< T > &	image,
		const vgl_point_3d< double > &	p,
		unsigned	plane = 0,
		T	outval = 0
	)		[inline]

Compute trilinear interpolation at p(x,y,z) in world coordinates, with bound checks.

Interpolates given plane of image.image() at image.world2im(p). If p is outside interpolatable image region, returns zero or outval

template<class T >

double vimt3d_trilin_interp_safe_extend	(	const vimt3d_image_3d_of< T > &	image,
		const vgl_point_3d< double > &	p,
		unsigned	plane = 0
	)		[inline]

Compute trilinear interpolation at p(x,y,z) in world coordinates, using the nearest valid value if out of bounds.

Interpolates given plane of image.image() at image.world2im(p). If p is outside safe interpolatable image region, nearest pixel value is returned.
