Line Removal (Standard)

This image enhancement removes horizontal or vertical lines from scanned images.

Show me an example.

 Using Line Removal 

1. Select the Image Processing node in the Scanning Explorer Pane.
2. Select Line Removal in the Document Properties Pane.
3. In the configuration wizard, specify the pages this enhancement will be applied to.

   

4. Select Next: Line Orientation.
5. Specify whether horizontal or vertical lines will be removed.

   

   Tip: To remove both, add an additional Line Removal enhancement to your scanning session.

6. Select Next: Minimum Line Size.
7. Define the smallest line that should be removed by specifying the minimum number of pixels printed in a row (vertically or horizontally, depending on your selection in Step 5). Lines equal to or larger than the specified size will be removed. Give me an example.

   Example: Selecting Short (75) removes all lines 75 pixels or longer in length.

   

8. Select Next: Maximum Line Thickness.

9. Define the maximum thickness (in pixels) a line can reach and still be removed. Give me an example.

   Example: Selecting Thin (10) removes all lines that are 10 or more pixels thick.

   

10. Select Next: Maximum Line Gap.

11. Specify the maximum amount of space (in pixels) that can exist between two line segments. Segments separated by more space than the size specified will not be removed. This option compensates for lines that have been fragmented due to a poor quality image.

    

12. Select Next: Excess Line Cleanup.

13. The area surrounding a poor quality line often contains stray marks. This option defines a region (in pixels) around the line from which stray marks will be removed. Give me an example.

    Example: Selecting Medium (2) removes all stray marks located within two pixels from a line.

    

14. Select Next: Character Reconstruction.

15. Characters that intersect lines may be damaged during line removal. This option repairs any damaged characters. Specify the maximum reconstruction width (in pixels).

    

    Tip: If damaged characters are not properly repaired after processing, select a higher value. If characters are improperly repaired, select a lower value.

16. Click Finish.

17. Optional: To preview how this enhancement will affect scanned images, select Test Process.

    Tip: For the best results, add a custom sample image before testing.
