Function Documentation

template<class T >

void vimt3d_gauss_reduce	(	const vimt3d_image_3d_of< T > &	src,
		vimt3d_image_3d_of< T > &	dst,
		vimt3d_image_3d_of< T > &	work1,
		vimt3d_image_3d_of< T > &	work2
	)

Smooth and subsample src_im to produce dest_im.

Applies filter in i,j and k directions, then samples every other pixel. Resulting image is (ni+1)/2 x (nj+1)/2 x (nk+1)/2. Transform is modified by a scaling factor of 0.5. An image can be reduced in-place, by having src_im and dest_im pointing to the same image. Requires client to provide 2 workspace images.

template<class T >

void vimt3d_gauss_reduce	(	const vimt3d_image_3d_of< T > &	src,
		vimt3d_image_3d_of< T > &	dst
	)

Smooth and subsample src_im to produce dest_im.

This simple overload does not require client to provide 2 workspace images.
