Abstract
New equations are derived for the perfect reconstruction of the boundary regions of a subband processed image. These equations are valid for filter banks with an arbitrary number of filters, having arbitrary nonlinear phase, and allowing any border extension method in the analysis section. The filter bank is maximally decimated in a wide sense, i.e., the sum of samples among the subbands is equal to the sum of the image samples, without having to store extended subband signals
