Returns the horizontal analysis wavelet filters used in each level, for the specified component and tile. 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.
