International Classification:

G06K 9/00

Abstract:

There is provided a method to identify structure of a native PDF document. The method comprises: obtaining a native PDF document having a first line to start a table and a second line to end the table; detecting a value of a physical feature of the native PDF document, wherein the physical feature has a corresponding weighting factor; initiating a value to the weighting factor; assigning a first status for the first line and a second status for the second line based on (a) the physical feature and (b) the weighting factor; and identifying a location of the table on native PDF document from the first status and the second status, thus yielding an identified location of the table.
