Abstract
Digital matrices, for example digitized images, are enhanced by comparing a matrix to be enhanced with plural enhancement patterns for each position in the matrix of each element of the matrix to produce pattern codes commensurate with the matches with the enhancement patterns. The pattern codes are employed to generate plural enhancement decisions for each element of the matrix and these enhancement decisions are combined to provide a single enhancement action for each element of the matrix.
