LS2W (version 1.3.6)

convertimwd: Convert a non-decimated imwd object to a wst2D object.

Description

Converting from a spatially ordered imwd object to a packet-ordered wst2D object.

Usage

convertimwd(imwd, ...)

Value

An object of class wst2D

Arguments

imwd

A imwd type object obtained by a stationary wavelet transform, i.e. imwd$type must be "station".

...

Any additional arguments.

Details

Inverting a 2-D non-decimated wavelet transform requires that the output is structured as a packet ordered transform. This function allows us to convert from the non-decimated (time ordered) imwd object to the packet ordered wst2D object. The function extracts information at a given scale/direction from the imwd object, converts it into the appropriate format and inserts it in the appropriate location of a (null) wst2D object. This function is used when simulating an LS2W process within the function LS2Wsim.cddews and does not need to be used separately.
