Abstract
A ballot tabulation device includes a scanner operable to obtain an image of at least a portion of a paper ballot that includes a voter response area. A processor applies a virtual template to the image to identify a center point for the voter response area. The virtual template comprises a set of characteristic points positioned in predetermined locations in relation to the center point of the voter response area, wherein the characteristic points comprise points that are common to a plurality of sample ballot images. The processor also defines a response window that is centered on the center point of the voter response area, and analyzes the response window to determine if the voter response area is marked by a voter.
