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.
