Abstract
Systems and methods systems and methods for edge detection during an imaging operation are disclosed. In an exemplary implementation, a method may include subdividing an imaging area into a plurality of border detection zones. The method may also include scanning the imaging area including media to be scanned to obtain optical data for each of the plurality of border detection zones. The method may also include identifying at least one edge of the media based on change in the optical data between directly adjacent border detection zones, where the change indicates detection of a moiré pattern.
Claims15
A method for edge detection during an imaging operation, comprising:
- subdividing an imaging area into a plurality of border detection zones;
- scanning the imaging area including media to be scanned to obtain optical data for each of the plurality of border detection zones;
- and
- identifying at least one edge of the media based on change in the optical data between directly adjacent border detection zones, where the change indicates detection of a moiré pattern.
A system for edge detection during an imaging operation, comprising:
- an imaging area including a plurality of border detection zones;
- a light source and light detector configured to scan the imaging area including media to be scanned and to obtain optical data for each of the plurality of border detection zones;
- and
- program code executable to identify at least one edge of the media based on change in the optical data between directly adjacent border detection zones, where the change indicates detection of a moiré pattern.
