When repurposing a document, a processor reads a document having multiple pages and extracts three samples of the multiple pages of the document. For each of the three samples, the processor compares sequential pages within a respective sample to identify a pattern of markers, such as page numbers. A marker is found by splitting a page into smaller regions and 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. The processor removes the markers based on identified patterns for each respective sample of the document.
