wavethresh (version 4.6.1)

nv.object: Node vector objects.

Description

These are objects of classes

nv

They represent a basis in a packet-ordered non-decimated wavelet transform object.

Value

• The following components must be included in a legitimate `nv' object.
• node.list
  This is a complicated structure composed of one-dimensional array of nv$nlevelsWT lists. Each item in the array is itself a list having two components$upperctrl and upperl. Each component is described as follows: [object Object],[object Object],[object Object]

GENERATION

This class of objects is returned from the MaNoVe.wst and numtonv functions. The former returns the minimum entropy basis (most sparse basis) obtained using the Coifman-Wickerhauser, 1992 algorithm. The latter permits selection of a basis by an index number.

METHODS

The nv class of objects has methods for the following generic functions: print, nlevelsWT, InvBasis,

Details

A nv object is a description of a basis which is a path through a packet ordered non-decimated wavelet transform. To view the basis just print it! See the examples in numtonv for a print out of its structure. A similar object exists for describing a basis in a wavelet packet object see nvwp.
