Abstract
A background detection process that analyzes background information for the purpose of limiting the impact of intensity information obtained from non-document areas includes: identifying a first white peak from pixels within a first document region; identifying a second white peak from pixels within a second document region; determining if the first white peak was identified using image data from outside of the input document; and if so, identifying a third white peak from pixels within the first document region based on the second white peak.
