Volume processing pipeline for automatic page extraction. Within pre-processing (blue boxes), the volume is denoised, binarized and overlapping pages are separated. Next, the pages are smoothed and holes are filled iteratively (green boxes). A texturing step stores the maximum value along the height of a page in a 2-D image resulting in the final 2-D mapped page (orange boxes).
