Abstract:
An imaging system includes two sets of cameras: a first set for capturing optical mark or optical character recognition data and a second set for capturing visual images. Full visual images of pages containing answers to open-ended questions are retained and are retrievable by a reader such that an area of interest wherein the answer is expected is displayed, but the remaining area is also available for viewing. The system permits the alignment of a page based upon edge detection if the page contains only an open-ended answer, obviating the need for timing tracks. Hardware and software elements cooperate to store the image temporarily in a server having a response time commensurate with the scanner. The image is then processed with the use of high-performance index imaging for optical storage and retrieval, and then routed to a long-term storage device.
