public final class DualScaling2_4
extends MultiscaleFunction
implements Cloneable
Cohen-Daubechies-Feauveau with N=2 and Ntilde=4 adapted to the interval by Deslauriers-Dubuc-Lemire

Constructor Index

o DualScaling2_4()
o DualScaling2_4(int, int)

Method Index

o clone()
Return a copy of this object
o dimension()
Number of scaling functions at scale where this scaling function belongs.
o dimension(int)
Starting with dimension() scaling functions and going jfin scales ahead (iterating jfin times), tells you how many scaling functions you'll have.
o equals(Object)
Check if another object is equal to this DualScaling2_4 object
o evaluate(int)
Return as an array the sampled values of the function
o getFilterType()
This method is used to compute how the number of scaling functions changes from on scale to the other.
o position()
Tells you what is the number of this scaling function.
o setParameters(int, int)
Set the parameters for this object
o toString()
Return a String representation of the object

Constructors

o DualScaling2_4 
 public DualScaling2_4(int N0,
                       int K)
o DualScaling2_4 
 public DualScaling2_4()

Methods

o equals 
 public boolean equals(Object a)
Check if another object is equal to this DualScaling2_4 object

Overrides:
equals in class MultiscaleFunction
o toString 
 public String toString()
Return a String representation of the object

Overrides:
toString in class MultiscaleFunction
o getFilterType 
 public int getFilterType()
This method is used to compute how the number of scaling functions changes from on scale to the other. Basically, if you have k scaling function and a Filter of type t, you'll have 2*k+t scaling functions at the next scale (dyadic case). Notice that this method assumes that one is working with the dyadic grid while the method "previousDimension" define in the interface "Filter" doesn't.

Overrides:
getFilterType in class MultiscaleFunction
o clone 
 public Object clone()
Return a copy of this object

Overrides:
clone in class MultiscaleFunction
o setParameters 
 public void setParameters(int N0,
                           int K)
Set the parameters for this object

Parameters:
N0 - number of scaling function on the scale of this object
K - position or number of this object
Throws: IllegalScalingException
if N0 is not large enough
o evaluate 
 public double[] evaluate(int j1)
Return as an array the sampled values of the function

Parameters:
j - number of iterations
Overrides:
evaluate in class MultiscaleFunction
o dimension 
 public int dimension(int jfin)
Starting with dimension() scaling functions and going jfin scales ahead (iterating jfin times), tells you how many scaling functions you'll have.

Parameters:
jfin - number of iterations
Overrides:
dimension in class MultiscaleFunction
o dimension 
 public int dimension()
Number of scaling functions at scale where this scaling function belongs.

Overrides:
dimension in class MultiscaleFunction
o position 
 public int position()
Tells you what is the number of this scaling function. Scaling functions are numbered from left to right with the one at the left boundary being noted 0.
