template<class srcT , class destT , class accumT >

void vil_exp_grad_filter_1d ( const srcT *  src, std::ptrdiff_t  sstep, destT *  dest, std::ptrdiff_t  dstep, int  n, accumT  k  )

inline

Apply exponential gradient filter to 1D data. Form: sign(i)*exp(c*|i|).

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