Investigating historical documents makes it neces-sary to use special imaging systems. We already showed in an earlier work that it is possible to use common 3-D X-ray CT scanners for the reconstruction of historical documents written with iron gall ink. Our tests were based on a self-made book which was scanned and investigated without opening or page-turning. However, when analyzing the reconstruction results, we faced the problem of a proper automatic extraction of single pages within the volume in an acceptable time without losing information of the writings. In this paper, we present a robust and efficient algorithm for the extraction of book pages from the original 3-D volume. This step is a necessary prerequisite for a possible identification of the writing. Our method delivers high quality results for our book model and can be easily adapted to other imaging modalities. We show that it performs well even for an extreme case with low resolution input data and wavy pages.
