Two-dimensional recursive filter design using differential correction
Dan E. Dudgeon · IEEE Transactions on Acoustics Speech and Signal Processing · 1975
This paper is based upon a presentation given at the 1974 Arden House Digital Signal Processing Workshop. The presentation discussed a method for designing two-dimensional recursive digital filters using a differential correction algorithm. A brief description of the algorithm and some design examples will be presented here. This design approach is compared to a similar approach used by Bednar and Farmer [1].
