CSJ2K.j2k.wavelet.analysis.SubbandAn.-ctor

SubbandAn Constructor

SubbandAn()

Creates a SubbandAn element with all the default values. The dimensions are (0,0) and the upper left corner is (0,0).

Declaration

public SubbandAn()

SubbandAn(int, int, int, int, int, WaveletFilter[], WaveletFilter[])

Creates the top-level node and the entire subband tree, with the top-level dimensions, the number of decompositions, and the decomposition tree as specified.

       <p>This constructor just calls the same constructor of the super class,
       and then calculates the L2-norm (or energy weight) of each leaf.</p>

       <p>This constructor does not initialize the value of the magBits or
       stepWMSE member variables. This variables are normally initialized by
       the quantizer (see Quantizer).</p>

Declaration

public SubbandAn(int w, int h, int ulcx, int ulcy, int lvls, WaveletFilter[] hfilters, WaveletFilter[] vfilters)

Parameters

Type	Name	Description
int	w	The top-level width
int	h	The top-level height
int	ulcx	The horizontal coordinate of the upper-left corner with respect to the canvas origin, in the component grid.
int	ulcy	The vertical coordinate of the upper-left corner with respect to the canvas origin, in the component grid.
int	lvls	The number of levels (or LL decompositions) in the tree.
WaveletFilter[]	hfilters	The horizontal wavelet analysis filters for each resolution level, starting at resolution level 0.
WaveletFilter[]	vfilters	The vertical wavelet analysis filters for each resolution level, starting at resolution level 0.
