This paper considers the optimal design and implementation of two-dimensional, nonrecursive digital filters for use in the processing of radiographic images. A stochastic system model is used for the image-forming process, and the filter is designed to a mean-square error criterion. Both the design algorithm and filter realization are mechanized by using a Fast Fourier Transform code, thereby ensuring the computational efficiency of the method.
