Abstract
The present invention is a method for automating the design of pattern matching templates used to implement a print quality enhancement filter that preserves image density More particularly, the method is directed to the use of a representative set of page description language decomposed or scanned training documents, and statistical data derived therefrom, in an automated process that generates one or more sets of template-pattern pairs that are used as filters for resolution enhancement and/or conversion of bitmap images.
