An adaptive image enhancement filter includes a template matching module for comparing an observed pixel pattern comprising a target pixel and one or more neighboring pixels to a set of templates to determine if the observed pixel pattern matches any of the templates. The template matching module generates a match identifier signal indicating which of the templates, if any, the observed pixel pattern is found to match. Based on this match identifier, a signal generation module provides an enhanced output signal for the target pixel. The template matching and/or the signal generation modules can be independently modified to adapt to changing conditions as identified by signals identifying image attributes and marking process attributes.
