`AutoCorrelationResampling.ac_resample`

— Method`ac_resample(ac, ratio[; filter])`

Resample three-dimensional autocorrelation function `ac`

by a ratio of `ratio`

times along the third axis, i.e. `ac`

of shape `(x,y,z)`

becomes an array of shape `(x,y,ratio * z)`

.

`AutoCorrelationResampling.filter_coeffs`

— Method`filter_coeffs(length)`

Get coefficients of symmetrical low-pass FIR filter of length `2length-1`

which maps autocorrelation functions to autocorrelation functions. Argument `length`

being equal to `n`

is enough for upscaling autocorrelations function `n`

times.
