Detailed Description

Sample image with nearest neighbour interpolation in one image and place in another.

Author:

dac

The vil nearest neighbour source files were derived from the corresponding vil bilin files, thus the vil bilin/bicub/nearest source files are very similar. If you modify something in this file, there is a corresponding bicub/bilin file that would likely also benefit from the same change.

void vil_resample_nearest	(	const vil_image_view< sType > &	src_image,
		vil_image_view< dType > &	dest_image,
		double	x0,
		double	y0,
		double	dx1,
		double	dy1,
		double	dx2,
		double	dy2,
		int	n1,
		int	n2
	)

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

dest_image(i,j,p) is sampled from the src_image at (x0+i.dx1+j.dx2,y0+i.dy1+j.dy2), where i=[0..n1-1], j=[0..n2-1] dest_image resized to (n1,n2,src_image.nplanes()) Points outside image return zero.

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

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