ABSTRACT An improved method and apparatus for digital image processing is disclosed which permits greater effic- iency in implementation of digital filtering techniques. In one implementation specially selected small generating kernels, or masks, are sequentially convolved with a data array of pixels representative of a particular image for more efficient restoration, enhancement or other conven- tional digital image processing techniques. The small generating kernels may be varied for each sequential con- volution. In some implementations the output of each sequential convolution may be weighted in accordance with the filtering desired.
