Name | Description | |
---|---|---|
AnHighNegSupport | Overridden. Returns the negative support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction. | |
AnHighPosSupport | Overridden. Returns the positive support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction. | |
AnLowNegSupport | Overridden. Returns the negative support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction. | |
AnLowPosSupport | Overridden. Returns the positive support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction. | |
DataType | Returns the type of data on which this filter works, as defined in the DataBlk interface, which is always TYPE_FLOAT for this class. (Inherited from CSJ2K.j2k.wavelet.analysis.AnWTFilterFloat) | |
FilterType | Overridden. Returns the type of filter used according to the FilterTypes interface(W9x7). | |
ImplType | Overridden. 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. | |
Reversible | Overridden. Returns the reversibility of the filter. A filter is considered reversible if it is suitable for lossless coding. | |
SynHighNegSupport | Overridden. | |
SynHighPosSupport | Overridden. | |
SynLowNegSupport | Overridden. | |
SynLowPosSupport | Overridden. |

analyze_hpf | Overloaded. Overridden. The general version of the analyze_hpf() method, it just calls the specialized version. See the description of the analyze_hpf() method of the AnWTFilter class for more details. | |
analyze_lpf | Overloaded. Overridden. The general version of the analyze_lpf() method, it just calls the specialized version. See the description of the analyze_lpf() method of the AnWTFilter class for more details. | |

getHPSynthesisFilter | Overridden. | |
getHPSynWaveForm | Returns the equivalent high-pass synthesis waveform of a cascade of filters, given the syhthesis waveform of the previous stage. This is the result of upsampling 'in' by 2, and concolving it with the high-pass synthesis waveform of the filter. The length of the returned signal is 2*in_l+hp_l-2, where in_l is the length of 'in' and 'hp_l' is the lengthg of the high-pass synthesis filter.
The length of the high-pass synthesis filter is getSynHighNegSupport()+getSynHighPosSupport(). (Inherited from CSJ2K.j2k.wavelet.analysis.AnWTFilter) | |
getLPSynthesisFilter | Overridden. | |
getLPSynWaveForm | Returns the equivalent low-pass synthesis waveform of a cascade of filters, given the syhthesis waveform of the previous stage. This is the result of upsampling 'in' by 2, and concolving it with the low-pass synthesis waveform of the filter. The length of the returned signal is 2*in_l+lp_l-2, where in_l is the length of 'in' and 'lp_l' is the lengthg of the low-pass synthesis filter.
The length of the low-pass synthesis filter is getSynLowNegSupport()+getSynLowPosSupport(). (Inherited from CSJ2K.j2k.wavelet.analysis.AnWTFilter) | |
isSameAsFullWT | Overridden. | |
