- public final class Wavelet8
- extends MultiscaleFunction
- implements Cloneable
Daubechies wavelets adapted to the
interval by Meyer. Thanks to Pierre Vial
for the filters.
-
Wavelet8()
-
-
Wavelet8(int, int)
-
-
clone()
- Return a copy of this object
-
dimension()
- Number of scaling functions at scale where this
wavelet belongs.
-
dimension(int)
- Given that the wavelet is written in terms of
a scale containing dimension() scaling functions and
going jfin scales ahead (iterating jfin times),
tells you how many scaling functions you'll need.
-
equals(Object)
- Check if another object is equal to this
Wavelet8 object
-
evaluate(int)
- Return as an array the sampled values
of the function
-
getFilterType()
- This method is used to compute
how the number of scaling functions
changes from on scale to the other.
-
position()
- Tells you what is the number of this
wavelet.
-
setParameters(int, int)
- Set the parameters for this object
-
toString()
- Return a String representation
of the object
Wavelet8
public Wavelet8(int N0,
int K)
Wavelet8
public Wavelet8()
toString
public String toString()
- Return a String representation
of the object
- Overrides:
- toString in class MultiscaleFunction
equals
public boolean equals(Object a)
- Check if another object is equal to this
Wavelet8 object
- Overrides:
- equals in class MultiscaleFunction
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
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
clone
public Object clone()
- Return a copy of this object
- Overrides:
- clone in class MultiscaleFunction
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
dimension
public int dimension(int jfin)
- Given that the wavelet is written in terms of
a scale containing dimension() scaling functions and
going jfin scales ahead (iterating jfin times),
tells you how many scaling functions you'll need.
- Parameters:
- jfin - number of iterations
- Overrides:
- dimension in class MultiscaleFunction
dimension
public int dimension()
- Number of scaling functions at scale where this
wavelet belongs.
- Overrides:
- dimension in class MultiscaleFunction
position
public int position()
- Tells you what is the number of this
wavelet. Wavelets are numbered from left
to right with the one at the left
boundary being noted 0.
