Detailed Description

Coefficients for Vliet-Young-Verbeek Gaussian approximation.

The vyv_coeffs struct stores the coefficients for the recursive filter of order K. This struct allows to precompute these filter coefficients separately from actually performing the filtering so that filtering may be performed multiple times using the same precomputed coefficients.

This coefficients struct is precomputed by vyv_precomp() and then used by vyv_gaussian_conv() or vyv_gaussian_conv_image().
