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.

Function Documentation

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) Definition at line 81 of file brip_vil_ops.h.

template<class T> 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 neigborhood. Definition at line 30 of file brip_vil_ops.h.
