vil_exp_filter_1d()

template<class srcT , class destT , class accumT >

void vil_exp_filter_1d ( const srcT *  src, std::ptrdiff_t  sstep, destT *  dest, std::ptrdiff_t  dstep, int  n, accumT  k  )

inline

Apply exponential filter to 1D data.

Apply filter to n values src[i*sstep] to produce output dest[i*dstep] Symmetric exponential filter of the form exp(c*|x|) applied. c=log(k) Uses fast recursive implementation.

template<class srcT , class destT , class accumT >

void vil_exp_filter_i ( const vil_image_view< srcT > &  src_im, vil_image_view< destT > &  dest_im, accumT  k  )

inline

Apply exponential filter along i to src_im to produce dest_im.

Symmetric exponential filter of the form exp(c*|i|) applied. c=log(k) Uses fast recursive implementation.
