Abstract

A technique is described for designing two-dimensional finite-length impulse response digital filters using linear programming. The principal advantage of the technique is the ability to design a filter while controlling aspects of the spatial domain and the frequency domain simultaneously. The frequency response of the filter can be smoothed, for example, by forcing the magnitude of the impulse response to decrease sequentially from the center of the filter to the edges. This smoothing technique offers the additional advantage of requiring only three directions of the frequency response to be specified. The technique has been successfully used to design image enhancement filters for a wide range of imagery. Typical image enhancement filters designed using this method are presented.
