摘要: Dropping out of color form backgrounds from images completed forms to obtain dropout retaining only the respondent information. In one embodiment, a image processing method (100) includes retrieving (102) template image, (104) registering (106) against another establish correspondence between pixels in and images, dilating (108) performing (110) including comparing (112) corresponding dilated determining (114) whether keep by applying (116) geometric solid threshold comparison assess both similarity relative darkness, removing (118) based on such comparison.
