Abstract :
Summary form only given. A novel approach to the design of perfect-reconstruction 2D mirror image filter banks, using auxiliary channel(s), is proposed. It is assumed that the filters are separable and identical in both directions. It has been shown that the structure can provide perfect reconstruction
