Abstract

Claims (24)

1. A method of correcting errors made while completing a printed form, comprising:

scanning by a scanner the printed form to create a first digital image of the printed form;

displaying the first digital image of the printed form to the user on a display;

receiving user input indicating one or more selected regions of the printed form;

expanding a user selected region to encompass undesired markings that extend outside the boundaries of the user selected region;

digitally whiting out the selected regions of the printed form to create a corrected image; and

outputting the corrected image to an output device.

2. The method of claim 1 , wherein expanding a user selected region comprises detecting the edge of the undesired markings that extend outside the boundaries of the user selected region with an edge detection algorithm.

3. A computer arrangement for digitally correcting mistakes made on printed forms, said device comprising:

a display; and

a processor configured to:

output a first digital image of the printed form to said display;

receive user selection input indicating one or more selected regions of the printed form; and

expand a user selected region to encompass undesired markings that extend outside the boundaries of the user selected region;

digitally whiteout the selected regions of the printed form to create a corrected image; and

output the corrected image to an output device.

4. The computer arrangement of claim 3 , wherein the processor expands the user selected region using an edge detection algorithm to detect undesired markings that extend outside the boundaries of the user selected region.

5. A computer readable media containing code executable on a computer, said code comprising:

code for outputting a first digital image of a printed form to a display of said computer;

code for receiving user selection input indicating one or more selected regions of the printed form; and

code for expanding a user selected region to encompass undesired markings that extend outside the boundaries of the user selected region;

code for digitally whiting out the selected regions of the printed form to create a corrected image; and

code for outputting the corrected image to an output device connected to the computer.

6. The computer readable media of claim 5 , wherein the code for expanding the user selected region executes an edge detection algorithm to detect undesired markings that extend outside the boundaries of the user selected region.
