For financial applications, the set of recognized characters can be limited to
numeric symbols, in which case only the characters '0' to '9' and some punctua-
tion symbols such as '.', ',' etc. will be recognized. Any chance of recognition
errors such as the confusion between '5' and "S", '0' and "O", '9' and "g", '8' and
"B" etc. is eliminated.
Fully customized character sets can be programmed by the user with the
"Output Subset" button on the toolbar. An example is creating an OCR-B charac-
ter set which limits recognition to the numerals and the symbols "<", ">" and "+".
(OCR-B is at the same time a highly specialized typeface used only in financial
documents such as preprinted checks, bank statements etc. I.R.I.S. has a spe-
cialized version of the IRISPen for the financial market.)
Selecting a limited character set not only increases recognition accuracy but
also speeds up the recognition process somewhat.
The reading modes "Black-and-White Bitmap to Clipboard" and "Greyscale
Bitmap to Clipboard" offer a direct way of inserting graphics in documents. Us-
ing the Windows clipboard, the user pastes the scanned image directly in his
active application. After the scanning, a blinking status window displays the mes-
sage "Image in clipboard" for a few seconds. As the image is sent directly to the
Windows clipboard, it cannot be retouched.
(The user can also enable the scan test mode and save graphics in a Windows
bitmap (BMP) file with the button "Save Image". In this case, he produces a
graphic file which can be retouched and should be inserted in his documents later
on.)
Selecting the reading mode "Bar Codes" or "Handprinting" suffices to scan
bar codes and handprinted character strings. Contrary to most bar code readers,
the user does not have to indicate which bar code “symbology” he is going to
read. The IRISPen software detects fully automatically which bar code type has
been scanned. As far as the user is concerned, the symbology is transparent and
various bar code types can be mixed without any consequence. The handprinting
technology supports all natural writing styles - American and European. Contrary
to many handwriting recognition solutions, no training phase or imposed style is
required.
