void vil3d_resample_trilinear	(	const vil3d_image_view< S > &	src_image,
		vil3d_image_view< T > &	dest_image,
		double	x0,
		double	y0,

		T	outval = 0,
		double	edge_tol = 0
	)

Sample grid of points in one image and place in another, using trilinear interpolation.

dest_image(i,j,k,p) is sampled from the src_image at (x0+i.dx1+j.dx2+k.dx3, y0+i.dy1+j.dy2+k.dy3, z0+i.dz1+j.dz2+k.dz3), where i=[0..n1-1], j=[0..n2-1], k=[0..n3-1]. dest_image resized to (n1,n2,n3,src_image.nplanes()) Points outside image return zero or outval

		vil3d_image_view< T > &	dest_image,
		int	n1,
		int	n2,
		int	n3
	)

Resample image to a specified dimensions (n1 * n2 * n3).

template<class T >

void vil3d_resample_trilinear	(	const vil3d_image_view< T > &	src_image,
		vil3d_image_view< T > &	dst_image,
		const double	dx,
		const double	dy,
		const double	dz
	)

Resample a 3D image by a different factor in each dimension.

dst_image resized by factors dx, dy, dz.

Note:

The upper image boundaries are extended.

Parameters:

dx	Scaling factor >1
dy	Scaling factor >1
dz	Scaling factor >1 dst_image(i, j, k, p) is sampled from src_image(i/dx, j/dy, k/dz, p). Interpolated values are rounded when the type T is smaller than double.

	)

Sample grid of points in one image and place in another, using trilinear interpolation and edge extension.

dest_image(i,j,k,p) is sampled from the src_image at (x0+i.dx1+j.dx2+k.dx3, y0+i.dy1+j.dy2+k.dy3, z0+i.dz1+j.dz2+k.dz3), where i=[0..n1-1], j=[0..n2-1], k=[0..n3-1]. dest_image resized to (n1,n2,n3,src_image.nplanes()) Points outside src_image return the value of the nearest valid pixel.

void vil3d_resample_trilinear_scale_2	(	const vil3d_image_view< T > &	src_image,
		vil3d_image_view< T > &	dst_image
	)

Resample a 3D image by a factor of 2 in each dimension.

dst_image is resized to 2*src_image.n?()-1 in each direction. Interpolated values are truncated when the type T is smaller than double.
