Method and system for determining page numbers of page images

A computer-implemented system to facilitate numbering images of pages of a document, comprising:

• a page image database operable to store page images organized according to an order in which pages appear in the document;
• a memory operable to store candidate page numbers extracted from the page images;
• a sequence merger component, coupled with the memory and the page image database, operable to merge two sequences of extracted candidate page numbers when a beginning candidate page number of a first sequence and an ending candidate page number of a second sequence differ by an amount that equals a number of page images in a gap between the first sequence and second sequence;
• an insert identifier component, coupled with the sequence merger component, operable to identify omitted page numbers forming the gap between the first sequence and second sequence;
• an assignment component, coupled with the insert identifier component, operable to assign consecutive page numbers to page images spanned by the gap, and labeling the page images in accordance with the extracted and assigned page numbers;
• and
• a completion threshold component, coupled with the assignment component, operable to determine and apply a completeness threshold to determine whether to abandon the numbering of page images.

A non-transitory computer-readable medium having encoded thereon instructions to number images of pages of a document, wherein the instructions, when executed by a computing apparatus, cause the computing apparatus to:

• obtain images of pages in an order in which the pages occur in a document;
• extract a number from at least one of the page images when the number is one different than a number extracted from an image of an adjacent page in the order in which the page occurs in the document;
• store the extracted numbers as sequences of consecutive numbers that correspond to the order in which the pages occur in the document;
• assign missing numbers to fill in gaps between the sequences when a count of the pages represented by a gap matches a count of the missing numbers that are needed to fill the gap;
• assign missing numbers to partially fill in gaps between the sequences when a count of the pages represented by the gap does not match the count of the missing numbers that are needed to fill in the gap, but differs by a substantially small amount;
• determine whether to abandon numbering of page images based on a variable completeness threshold;
• and
• label the page images with the extracted and assigned numbers.
