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. |
Name | Description | |

![]() | 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. |
![]() | Equals | |
![]() | GetHashCode | |
![]() | 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. |
![]() | ToString | Debugging method |
