CHAPTER 6

DJUSTING SCANNED DOCUMENTS

When opening or scanning extremely light or extremely dark

grayscale and color images, it may be necessary to adjust those

images before executing the recognition, in order to obtain

satisfactory OCR results.

To adjust images:

 Open or scan a color-grayscale document.

Make sure that the scanner settings are correct.

Important: the scanner settings and adjustment settings appear to

be the same but note that both sets of settings are applied at different

stages in the scan/recognition process.

 On the Process menu, click Adjust image.

Readiris uses intelligent binarization routines to convert color-

grayscale images into black-and-white images, which are used to

perform OCR on.
