Properties

Name Description
AnHighNegSupport

Returns the negative support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction.
AnHighPosSupport

Returns the positive support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction.
AnLowNegSupport

Returns the negative support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction.
AnLowPosSupport

Returns the positive support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction.
ImplType

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

Returns the reversibility of the filter. A filter is considered reversible if it is suitable for lossless coding.
SynHighNegSupport

Returns the negative support of the high-pass synthesis filter. That is the number of taps of the filter in the negative direction.
SynHighPosSupport

Returns the positive support of the high-pass synthesis filter. That is the number of taps of the filter in the negative direction.
SynLowNegSupport

Returns the negative support of the low-pass synthesis filter. That is the number of taps of the filter in the negative direction.
SynLowPosSupport

Returns the positive support of the low-pass synthesis filter. That is the number of taps of the filter in the negative direction.

Methods

Name Description
ToString()

Returns a string of information about the synthesis wavelet filter
isSameAsFullWT(int, int, int)

Returns true if the wavelet filter computes or uses the same "inner" subband coefficient as the full frame wavelet transform, and false otherwise. In particular, for block based transforms with reduced overlap, this method should return false. The term "inner" indicates that this applies only with respect to the coefficient that are not affected by image boundaries processings such as symmetric extension, since there is not reference method for this.

       <p>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.</p>
synthetize_hpf(float[], int, int, int, float[], int, int, int, float[], int, int)

A specific version of the synthetize_hpf() method that works on float data. See the general description of the synthetize_hpf() method in the SynWTFilter class for more details.
synthetize_lpf(float[], int, int, int, float[], int, int, int, float[], int, int)

A specific version of the synthetize_lpf() method that works on float data. See the general description of the synthetize_lpf() method in the SynWTFilter class for more details.
