Efficient design of two-dimensional recursive digital filters. Annual progress report
The digital processing of two-dimensional (2-D) data has found increasing application during the last ten years in a number of different areas such as processing of geological and seismological data (detection of oil and natural gas reserves), satellite-borne remote photography in the visible and infrared ranges (monitoring surface features, earth resources, environmental effects, and urban land use), and x-ray and gamma-ray photographs (medical and industrial diagnostics and physics). The need to filter two-dimensional data exists in each of the above application areas. Our investigations over the past year have been concerned with the problem of developing efficient methods for the design/implementation of stable 2-D recursive digital filters.
