Package jj2000.j2k.wavelet.synthesis
Class SynWTFilterInt
java.lang.Object
jj2000.j2k.wavelet.synthesis.SynWTFilter
jj2000.j2k.wavelet.synthesis.SynWTFilterInt
- All Implemented Interfaces:
Markers,WaveletFilter
- Direct Known Subclasses:
SynWTFilterIntLift5x3
This extends the synthesis wavelet filter general definitions of
SynWTFilter by adding methods that work for int data
specifically. Implementations that work on int data should inherit
from this class.
See the SynWTFilter class for details such as normalization, how to split odd-length signals, etc.
The advantage of using the specialized method is that no casts are performed.
