1. A non-transitory computer readable medium for repurposing a document, comprising instructions that when read and executed by a processor cause the processor to:
read a document having multiple pages;
extract three samples of the multiple pages of the document;
for each of the three samples, compare sequential pages within a respective sample to identify a pattern of markers, wherein a marker is found by splitting a page into smaller regions that are each smaller than the page, wherein each smaller region is searched for the marker and if the marker is not found continuing to split a smaller region into further smaller regions that are each smaller than the smaller region, and wherein each further smaller region is searched for the marker; and
remove the markers based on identified patterns for each respective sample of the document.
