Abstract

A method for counting or recounting an optically readable sheet may comprise receiving an image the sheet and displaying the received image of the sheet for determining from the displayed image of the sheet the marking of mark spaces therein. Indications of information decoded therefrom may be superimposed and/or provided by highlighting. The counting and/or recounting need not require handling of the original sheets.

Claims

1. A method for counting or for recounting or for counting and recounting selections marked on an optically readable sheet having one or more regions of choices and a plurality of mark spaces in each region in which one or more selections may be marked for each of one or more choices, each mark space being a space defined for marking a selection therein, the method comprising:

receiving an image of a sheet having one or more choice regions and a plurality of mark spaces thereon wherein the image of the sheet includes all of the mark spaces for the choice regions thereon and is in an image format;

displaying the image of the sheet on a display in human-perceivable form, whereby a human may view the image of the sheet including the one or more choice regions and the mark spaces thereon, including mark spaces that are marked;

receiving information decoded from the sheet of the mark spaces thereon that are marked;

determining from the image of the sheet that is displayed the mark spaces of the image of the sheet that are marked; and

in addition to said receiving an image of a sheet;

imaging the sheet for obtaining an independent image of the sheet, whereby the independent image is independent of the received image of the sheet;

decoding the independent image of the sheet for determining marked mark spaces thereon; and

comparing the received information of marked mark spaces decoded from the image of the sheet, the marked mark spaces determined from the displayed image of the sheet and the marked mark spaces determined from the independent image of the sheet, or any two thereof, to determine any differences there between.

2. The method of claim 1 further comprising:

repeating the steps of claim 1 for images of a plurality of sheets, and

recording the received information of marked mark spaces decoded from the images of the plurality of sheets, the received information determined from the displayed images of the plurality of sheets, and any differences there between.

3. The method of claim 1 further comprising:

highlighting or superimposing or highlighting and superimposing on the displayed image of the sheet an indication of the received information of marked mark spaces decoded from the image of the sheet;

or

decoding the marked mark spaces from the image of the sheet and highlighting or superimposing or highlighting and superimposing on the displayed image of the sheet an indication of the marked mark spaces decoded from the image of the sheet.

4. The method of claim 1 wherein said receiving information decoded from the image of the sheet includes:

decoding from the image of the sheet for each mark space whether the mark space is marked as a selection, wherein said decoding includes;

counting at least the number of dark pixels for each mark space; and

determining from the counts of at least the dark pixels for each mark space whether the mark space is unmarked or is marked as a selection.

5. The method of claim 4 wherein said determining from the counts of at least the dark pixels for each mark space comprises:

comparing the counts of at least the dark pixels for each mark space with a first predetermined threshold to determine whether the mark space is unmarked or is marked as a selection;

comparing the counts of at least the dark pixels for each mark space with a second predetermined threshold to determine whether the mark space is unmarked or is marked as a selection;

for each mark space for which one of the preceding two comparing steps determines that a mark space is unmarked and the other of the preceding two comparing steps determines that a mark space is marked as a selection;

highlighting or superimposing or highlighting and superimposing an indication of the different determination near each mark space on the displayed image of the sheet for which the determinations based on the first and second thresholds differ.

6. The method of claim 1 further comprising:

determining from the marked mark spaces whether there is an under selection or an over selection in any choice region; and

highlighting or superimposing or highlighting and superimposing on the choice region of the displayed image of the sheet an indication of the under selection or over selection therein.

7. The method of claim 1 wherein two or more mark spaces are associated with a choice region, each choice region having a given number of selections that may be made therein, and wherein said receiving information decoded from the image of the sheet further comprises:

counting the number of mark spaces for each choice region that are determined to be marked as a selection;

comparing the number of selections marked to the given number of selections; and

;

if the number of selections marked for a choice region is less than the given number, then providing an indication of an under selection on the displayed image for that choice region, or

if the number of selections marked for a choice region exceeds the given number, then providing an indication of an over selection on the displayed image for that choice region, or

if the number of selections marked for a choice region is less than the given number, then providing an indication of an under selection on the displayed image for that choice region, and if the number of selections marked for a choice region exceeds the given number, then providing an indication of an over selection on the displayed image for that choice region.
