public AnWTFilter[] getHFilters(int t, int c)
The horizontal analysis filters are returned in an array of AnWTFilter. Each element contains the horizontal filter for each resolution level starting with resolution level 1 (i.e. the analysis filter to go from resolution level 1 to resolution level 0). If there are less elements than the maximum resolution level, then the last element is assumed to be repeated.
t
- The tile index, in raster scan orderc
- The component index.public AnWTFilter[] getVFilters(int t, int c)
The vertical analysis filters are returned in an array of AnWTFilter. Each element contains the vertical filter for each resolution level starting with resolution level 1 (i.e. the analysis filter to go from resolution level 1 to resolution level 0). If there are less elements than the maximum resolution level, then the last element is assumed to be repeated.
