1. A method for generating a background peak for a scanned document, comprising: generating a first histogram from pixels within a first document area, the first document region representing a full page; generating a second histogram from pixels within a second document region; identifying a first white peak from the first histogram; identifying a second white peak from the second histogram; comparing the first white peak to at least one of a minimum threshold, a maximum threshold, and a threshold generated as a function of the second white peak; and identifying a third white peak from within a range of the first histogram defined by a function of the first white peak and by a function of the second white peak.
