For example, cutting columns apart and arranging them in proper sequence is recommended when pages are partially columnized. Users can improve the quality of recognition by hand-editing images to ensure that the content flows properly. InftyReader subdivides the document into text, math, tables, and figures and then uses different procedures to recognize each. Recognition can be improved by optimizing the scanner threshold so that fewer than 1% of characters are broken or touch other characters. Heavy users of InftyReader can improve the quality of recognition by editing scanned images to remove small extraneous scan defects and artifacts. Recognizing math characters requires much higher quality images than does standard OCR, and poor quality images will give correspondingly poor results. Save the scanned files as TIFF, GIF or PNG format. If possible, pages in books should be cut from the binding so they will lie flat on the scanner. The paper should be flat and carefully aligned in the scanner to avoid images that are fuzzy, skewed, or slanted. InftyReader can recognize only a high quality black-and-white (binary) image.įor paper documents, it is very important to scan the document in black and white (binary) mode and to use a resolution of at least 400 dpi.
