public interface WaveletFilter
Both analysis and filters must be able to return the extent of the negative and positive support for both synthesis and analysis sides. This simplifies the sue of some functionalities that need extra information about the filters.

filter.

int 
getAnHighPosSupport()

filter.

int 
getAnLowNegSupport()

filter.

int 
getAnLowPosSupport()

filter.

int 
getDataType()
Returns the type of data on which this filter works, as defined
in the DataBlk interface.

int 
getImplType()
Returns the implementation type of this filter, as defined in
this class, such as WT_FILTER_INT_LIFT, WT_FILTER_FLOAT_LIFT,
WT_FILTER_FLOAT_CONVOL.

int 
getSynHighNegSupport()
Returns the negative support of the highpass synthesis
filter.

int 
getSynHighPosSupport()
Returns the positive support of the highpass synthesis
filter.

int 
getSynLowNegSupport()
Returns the negative support of the lowpass synthesis
filter.

int 
getSynLowPosSupport()
Returns the positive support of the lowpass synthesis
filter.

boolean 
isReversible()
Returns the reversibility of the filter.

boolean 
isSameAsFullWT(int tailOvrlp,
int headOvrlp,
int inLen)
Returns true if the wavelet filter computes or uses the
same "inner" subband coefficient as the full frame wavelet transform,
and false otherwise.

boolean isSameAsFullWT(int tailOvrlp, int headOvrlp, int inLen)
The result depends on the length of the allowed overlap when compared to the overlap required by the wavelet filter. It also depends on how overlap processing is implemented in the wavelet filter.
tailOvrlp
 This is the number of samples in the input
signal before the first sample to filter that can be used for
overlap.headOvrlp
 This is the number of samples in the input
signal after the last sample to filter that can be used for
overlap.inLen
 This is the lenght of the input signal to filter.The
required number of samples in the input signal after the last sample
depends on the length of the input signal.Copyright © 2014 Open Microscopy Environment
