There is an ever increasing number of publications which do not
have the "traditional" layout where printed regions are rectangu-
lar. Text paragraphs and areas of graphic type may be of any shape,

underlining idea is to efficiently produce a flexible description (by
means of tiles) of the background space which surrounds the printed
regions in the page image under all the above conditions. Using this
description of space, the contours of printed regions are identified
with significant accuracy. The new approach is fast as there is no
need for skew detection and correction, and only few simple oper-
