This file contains several useful image operations originally defined in brip_float_ops for vil1 floating point images. Some of the original operations are covered in the new vil library, these are use when possible and not duplicated here.

template<class srcT , class destT >

void brip_gauss_filter	(	const vil_image_view< srcT > &	src_im,
		vil_image_view< destT > &	dest_im,
		double	sigma,
		unsigned int	k_size,
		vil_convolve_boundary_option	option
	)		`[inline]`

Filter an image with a gaussian kernel.

This is an ntap alternative to vil_gauss_filter_5tap The kernel is generated using vcl_exp instead of vnl_erf

Parameters:

sigma	The width of the gaussian
k_size	The number of elements in the 1D filter
option	The boundary option applied at all boundaries (see vil_convolve_1d)

void brip_sqrt_grad_singular_values	(	const vil_image_view< T > &	input,
		vil_image_view< T > &	output,
		unsigned	n
	)		`[inline]`

computes the conditioning of the 2n+1 x 2n+1 gradient neighborhood.
