Digital Image Processing

27 August, 2015 - 17:41

Digital image processing systems are computer-based systems for storage, retrieval, and presentation of images of real or simulated objects. In the typical business application, the images are usually documents.


After a document has been input, additional processing may take place. The user may enter additional data related to the document or that acts on data contained in, or associated with, the document. Recall that in Chapter 3 we discussed the move toward object-oriented databases that are capable of handling object data—such as images—and that we noted the move toward enabling object storage within relational databases. A major part of the demand for object-capable databases is the management of a vast array of document images. Linkages of these images into the enterprise system can make accessibility much easier as information can readily be distributed throughout the organization. In many advanced digital imaging systems, the content of the digital image may subsequently be manipulated as if it were directly entered into an application or retrieved from a database. For example, a scanned word processing document could be edited directly, or a purchase order changed to reflect the receipt of a backordered item. This is not always a desirable feature, as some business documents (e.g., contracts) should not be manipulable once they are digitally recorded.
