List of all members.
Public Member Functions
- VHFilter ()
- virtual ~VHFilter ()
- virtual void Split (const int xp, const int yp, const int xl, const int yl, CoeffArray &coeff_data)=0
- Split a subband into 4.
- virtual void Synth (const int xp, const int yp, const int xl, const int yl, CoeffArray &coeff_data)=0
- Create a single band from 4 quadrant bands.
- virtual int GetShift () const =0
- Return the value of the additional bitshift.
Protected Member Functions
- void Interleave (const int xp, const int yp, const int xl, const int yl, CoeffArray &coeff_data)
- Interleave data from separate subbands into even and odd positions for in-place calculation - called by Synth.
- void DeInterleave (const int xp, const int yp, const int xl, const int yl, CoeffArray &coeff_data)
- De-interleave data even and odd positions into separate subbands - called by Split.
- void ShiftRowLeft (CoeffType *row, int length, int shift)
- Shift all vals in Row by 'shift' bits to the left to increase accuracy by 'shift' bits. Used in Analysis stage of filter.
- void ShiftRowRight (CoeffType *row, int length, int shift)
- Shift all vals in Row by 'shift' bits to the right to counter the shift in the Analysis stage. This function is used in the Synthesis stage.
