Abstract
In this paper, we present a design method of directionally oriented 2-D filter (directional filters) and filter bank. At first, we consider the 2-D prototype passband filter. Next, using downsampling, we decimate the prototype filter coefficient and design directional filters. The passband regions of the component filters are wedge shaped and thus provide directional information. By using this method, we can reduce the number of filters which we must design. Finally, we show the 2-D filter bank structure with above-mentioned filter.
