The discrete Walsh transform is defined over a finite interval and produces undesirable blocking effects in digital image processing. It is shown how significant improvement can be obtained in eliminating the blocking problem by introducing the overlapping matrix Q and its false inverse Q for dyadic drift Walsh functions. This is applied to a two-dimensional overlapping sequency filter and an overlapping dyadic differentiation operator.<>
