| Abstract(in English) | A novel design method for non-separable two-dimensional filter banks based on the optimal approximation theory is presented by the extension from the 1-D filter bank design method. First, error measure of a 2-D filter bank, i.e. the supremum of absolute error between bandlimited input and corresponding output, is introduced In the sense of this error criterion, the method optimizes synthesis and analysis filter coefficients for given analysis filters. For the further reduction in the error, the above design method is applied again with replacing the given analysis filters by the derived synthesis filters, and these procedures are repeated until the error becomes sufficiently small. Moreover, balance of the analysis and synthesis filters is considered in order to achieve fast desendent of error. Design examples with diamond-shaped support show the effectiveness of the proposed methods. |
