Claim One:
1. A system, comprising: an imager for capturing first and second images of an object using light reflected off the object, the first image including illuminated pixels that are part of an object of interest and the second image including illuminated pixels that are not part of the object of interest; and a controller connected to the imager for defining and using one or more non-interpretation region in one of the first image and second image to reduce a number of artifacts in a final image, wherein the controller is configured to: compute a difference image between the first image and second image to remove the illuminated pixels that are not part of the object of interest, the difference image including illuminated pixels that are artifacts and the illuminated pixels that are part of the object of interest, wherein the illuminated pixels that are artifacts in the difference image correspond to the illuminated pixels that are not part of the object of interest in the second image; define the non-interpretation region to include the illuminated pixels that are artifacts in the difference image and non-illuminated pixels that are in proximity to the illuminated pixels that are artifacts in the difference image, wherein the illuminated pixels that are part of the object of interest in the difference image are excluded from the non-interpretation region; and eliminate the illuminated pixels that are artifacts in the difference image which are included in the defined non-interpretation region.
