Scanning: |
ADF: An Automatic Document Feeder allows multiple pages to enter a scanner without each page being placed separately. Some ADFs are built into scanners; others are add-on products. OmniPage accepts input from ADFs. This is useful for scheduled jobs.
Flatbed scanner: A scanner in which the paper remains stationary and the scanning head moves. Such scanners generally produce higher quality images than comparable sheetfed scanners. A flatbed scanner needs an ADF to scan multiple sheets automatically.
Autoscan: This is for scanning long documents with a flatbed scanner without an ADF. It starts new scans at regular user-defined intervals. A dialog box allows each pause to be lengthened or shortened.
Sheetfed scanner: A scanner in which the scanning head remains stationary and the paper moves. Such scanners usually occupy less space and have a built-in ADF, but generally a comparable flatbed scanner will produce higher quality images.
Dpi: Dot per inch (dpi) is a measure of the resolution (pixel density) of an image. The optimum resolution for OCR is 300 dpi.
Resolution: This is a measure of pixel density in an image. It is measured in dots per inch (dpi). OmniPage can accept images up to 600 dpi, but the ideal resolution for OCR is 300 dpi. Resolution can be specified for saving image files in the converter options dialog box.
Brightness: A measure of how dark or pale a scanned image will be. OCR quality depends heavily on good brightness settings. An image where letter shapes run together is too dark. When letter shapes are thin or broken, the image is too light. Brightness can be changed in the Image Enhancement window. Many scanners have an auto-brightness feature.
Contrast: A measure of how much difference there will be between light and dark parts of an image. OCR quality depends heavily on good brightness and contrast settings. Not all scanners allow manual adjustment of contrast. Contrast can be improved in the Image Enhancement window.
Scanner Wizard: A program that uses information from a user as well as pre-set settings to configure OmniPage to communicate with a scanner for the best possible scanning results.
Scanner drivers: Computer files created by a scanner manufacturer that allow communication between the scanner and the computer's operating system. Many scanner models have several versions of drivers that are each compatible with certain versions of Windows. Many scanner manufacturers have drivers on their web sites available for download.
Native User Interface: The scanner interface provided by your scanner manufacturer. By choosing to show the Native User Interface, it is possible to change the settings that the Scanner Wizard has set for the scanner.
TWAIN: Technology Without An Interesting Name. An accepted set of standards for many scanners and digital cameras. Scanners must be TWAIN compliant to function correctly with OmniPage. Scanner manufacturers can be asked which of their scanners are TWAIN compliant. |
Images: |
Zones: Areas enclosed by borders drawn over the page image in the Image Panel. Zones have a zone type and may have a zone contents value. Both can be automatically or manually assigned. Zoning, the creation of zones, can be done manually or automatically or with a combination of both. Areas inside Ignore zones are always ignored during OCR.
Auto-zoning: The automatic drawing of zones on a page image. Elements inside process zones and on a process background are auto-zoned. Auto-zoning is influenced by the original layout description setting. Alternatives to auto-zoning are manual or template zoning.
Manual zoning: This is the process of drawing user-defined zones on an image. Alternatives are auto-zoning or template zoning. Manual zoning can be done as part of manual processing, by interrupting automatic processing, or by running a workflow containing the Zone Images Manually step.
Zone properties: The Zone types and the Zone contents together constitute the Zone properties. Zone properties can be changed by right-clicking inside a zone for a shortcut menu.
Process zone: A page image area that will be auto-zoned and recognized. After processing it may result in one or more text, table or graphic zones. Page backgrounds can also be designated as "Process". |
Processing: |
OCR: Optical character recognition is the process of extracting text from an image. This image can result from scanning a paper document or opening an electronic image file. The text becomes computer-editable, so that it does not have to be retyped manually.
LFR: Logical Form RecognitionTM. A recognition algorithm used for form processing in OmniPage Professional. LFR runs on pages with Form as Layout Description and inside Form zones. Form editing tools are available only when LFR has run.
Workflow: A workflow consists of a series of steps and their settings. A workflow may include for example, a scanning, recognition, proofing and one or more saving steps. The Workflow Assistant serves for creating and modifying workflows. Steps are represented as icons and are offered for selection. In addition, workflows form an integral part of all jobs.
ODMA: Open Document Management Application Programming Interface. This interface makes the functionality of Document Management Systems (DMS) accessible for other programs. OmniPage is able to work with this interface.
Portable Document Format (PDF): A document format widely used in web pages and for displaying documents. OmniPage can open PDF files and create an editable version of their displayed texts. It can also save recognition results to five variants of PDF files: viewable only, viewable with image replacements of uncertain characters, viewable and searchable, viewable and editable, and edited. |
