1. A computer-implemented method for capturing a document, said method comprising: receiving, at a computing system, an image frame from a first image-capture device; comparing said received image frame with a previously captured image frame, wherein said comparing comprises one selected from the group consisting of motion filtering and determining the optical flow between said received image frame and said previously captured image frame; when said comparison indicates that said received image frame has stabilized relative to said previously captured image frame, determining if said received image frame is associated with a document; and when said determining indicates that said received image frame is associated with a document, capturing a document image associated with said image frame to a document buffer.
