BARCODE SDK - OCR SDK - DOCUMENT IMAGING
Recognition
Production imaging systems often rely on various recognition
technologies to enhance the speed and efficiency of the image
capture/data extraction process. The two prevalent methods
utilized today are barcode recognition and optical character recognition
(OCR).
Barcode
Anyone who has been to a grocery store has utilized barcodes. Barcodes help reduce data-entry errors and speed transaction entry.
In imaging, they provide a means of quickly obtaining information for
use in indexing or for use by an application. Imaging SDK's will
typically provide the ability to search for a barcode on a page,
recognize its symbology and recognize the data within.
Barcode symbologies are either 1-dimensional (with all the data is encoded in the horizontal width)
or 2-dimensional (with data encoded in the horizontal and vertical dimensions).
They include:
- Code 128
- Code 39 (a.k.a. 3 of 9)
- CODABAR
- Code 93
- UPC-A & -E
- PDF417 (2D)
OCR
OCR provides the ability to convert hardcopy text documents into code
that can be read and understood by computer applications. Most imaging SDK's provide recognition capabilities for most types of documents, including those produced on typewriters, dot-matrix printers, ink-jet printers, laser printers, as well as photocopied and faxed versions of any document.
When utilized in an application, OCR will acquire a page image as input and produce
recognized text in a variety of output formats.
