What algorithm would you suggest in getting this .pdf converted using a combination of reflow and/or two-column support?

That pdf file is really challenging. Current algorithm cannot correctly seperate non-convex regions overlapping both horizontally and vertically. There may exist good algorithms that can handle this case, but I don't know any of them at the moment. (I am not an expert in the field of document segmentation.) Also, such algorithm, if any, may probably increase processing time.
Of course, it is easy to segment the pdf file in a PDFRead-way (simply dividing a page into two regions.) I would include this over-simplified but robust segmentation method into PaperCrop as an option someday.
