(a) Exemplary X-ray volume xy-slice of the scanned book: The high resolution and the orientation of the pages in the volume make it impossible to read each page separately with the naked eye. Multiple pages are present in one slice such that a virtual flattening is necessary. (b) yz-slice of the volume–the pages are separated by air gaps and look like small vessels. (c) The same yz-slice after applying the volume binarization step–the pages are binarized but still contains overlaps and gaps. (d) The final output after page segmentation for the yz-slice of (b)–overlapping pages are separated and gaps are closed.
