All known Subclasses: jj2000.j2k.wavelet.analysis.ForwardWT,
| ForwWT | | public interface ForwWT extends WaveletTransform,ForwWTDataProps(Code) | | This interface extends the WaveletTransform with the
specifics of forward wavelet transforms. Classes that implement forward
wavelet transfoms should implement this interface.
This class does not define the methods to transfer data, just the
specifics to forward wavelet transform. Different data transfer methods are
evisageable for different transforms.

| Method Summary | |
| public int | getDecomp(int t, int c)
Returns the wavelet tree decomposition. | | public int | getDecompLevels(int t, int c)
Returns the number of decomposition levels that are applied to
obtain the LL band, in the specified tile-component. | | public AnWTFilter[] | getHorAnWaveletFilters(int t, int c)
Returns the horizontal analysis wavelet filters used in each
level, for the specified tile-component. | | public AnWTFilter[] | getVertAnWaveletFilters(int t, int c)
Returns the vertical analysis wavelet filters used in each
level, for the specified tile-component. |
| getDecomp | | public int getDecomp(int t, int c)(Code) | | Returns the wavelet tree decomposition. Only WT_DECOMP_DYADIC
is supported by JPEG 2000 part I.
Parameters:
t - The tile index
Parameters:
c - The index of the component. The wavelet decomposition. |
| getDecompLevels | | public int getDecompLevels(int t, int c)(Code) | | Returns the number of decomposition levels that are applied to
obtain the LL band, in the specified tile-component. A value of
0 means that no wavelet transform is applied.
Parameters:
t - The tile index
Parameters:
c - The index of the component. The number of decompositions applied to obtain the LLband (0 for no wavelet transform). |
| getHorAnWaveletFilters | | public AnWTFilter[] getHorAnWaveletFilters(int t, int c)(Code) | | Returns the horizontal analysis wavelet filters used in each
level, for the specified tile-component. The first element in
the array is the filter used to obtain the lowest resolution
(resolution level 0) subbands (i.e. lowest frequency LL
subband), the second element is the one used to generate the
resolution level 1 subbands, and so on. If there are less
elements in the array than the number of resolution levels,
then the last one is assumed to repeat itself.
The returned filters are applicable only to the specified
component and in the current tile.
The resolution level of a subband is the resolution level to
which a subband contributes, which is different from its
decomposition level.
Parameters:
t - The index of the tile for which to return the filters.
Parameters:
c - The index of the component for which to return thefilters. The horizontal analysis wavelet filters used in eachlevel. |
| getVertAnWaveletFilters | | public AnWTFilter[] getVertAnWaveletFilters(int t, int c)(Code) | | Returns the vertical analysis wavelet filters used in each
level, for the specified tile-component. The first element in
the array is the filter used to obtain the lowest resolution
(resolution level 0) subbands (i.e. lowest frequency LL
subband), the second element is the one used to generate the
resolution level 1 subbands, and so on. If there are less
elements in the array than the number of resolution levels,
then the last one is assumed to repeat itself.
The returned filters are applicable only to the specified
component and in the current tile.
The resolution level of a subband is the resolution level to
which a subband contributes, which is different from its
decomposition level.
Parameters:
t - The index of the tile for which to return the filters.
Parameters:
c - The index of the component for which to return thefilters. The vertical analysis wavelet filters used in eachlevel. |
