av.basis: Perform basis averaging for wst class object

In wavethresh: Wavelets Statistics and Transforms

Perform basis averaging for wst class object

Description

Note: that this function is not for direct user use. This function is a helper routine for the AvBasis.wst function which is the one that should be used by users.

This function works by recursion, essentially it merges the current levels C coefficients from one packet shift with its associated D coefficients, does the same for the other packet shift and then averages the two reconstructions to provide the C coefficients for the next level up.

Usage

av.basis(wst, level, ix1, ix2, filter)

Arguments

wst	The wst.object that you wish to basis average
level	The resolution level the function is currently operating at
ix1	Which "left" packet in the level you are accessing
ix2	Which "right" packet
filter	The wavelet filter details, see filter.select

Details

Description says all, see help page for AvBasis.wst.

Value

Returns the average basis reconstruction of a wst.object.
