Acoustics, Speech, and Signal Processing, IEEE International Conference on ICASSP '87.The article of record may be found at http://dx.doi.org/10.1109/ICASSP.1987.1169469A method of designing two-dimensional (2-D) FIR filters, using nonuniform frequency samples, is presented. The method is based on an extension of the DFT method of design, which uses uniform frequency samples. The proposed method, is based on an extension of Newton's interpolation method to 2-D. The proposed procedure has the attractive properties of permanence and recursive computation of the design parameters. A design procedure is given for 2-D FIR linear phase filters and an example is given
