Optimal design of dual-channel subband filter structures for video and image applications
This paper discusses the many and varied design considerations of a 2D digital subband filter bank implementation for orthogonal sampling structures, which enables the derivation of only two subbands rather than the usual four. In particular, the design trade-off and overall performance of a quadrature mirror filter pair, in combination with a 2D diagonal prefilter is explored and the ensuing problems of avoiding and compensating for aliasing within the subbands, as well as for the signal reconstruction process at the decoder are highlighted.
