A practical method of image enhancement by interactive digital filtering.
A generalized form of the Wiener digital filter is described in which the user interactively varies two filter parameters to produce any desired number of filtered versions of a given image with differing blends of sharpening and smoothing qualities. Filtering is performed sufficiently rapidly, even without use of an array processor, to make application of the filter truly interactive. Use of the filter is illustrated with typical nuclear medicine images.
